Basically the ingredients for human development and the country in general is Vocational and Technical education and this has been stressed in Ghana’s education system since Pre-independence. To this effect, this research seeks to determine using demonstration method of Teachings sewing to improve the skills of form 3 Fashion Designing students of Baworo Integrated Community Centre for Employable Skills. In this research, reviewed literature on opinions of other researchers and what other people have done and said on related articles or topics, analyzed the research design used, translate the data gathered in the study. The study was design to gather information from the school on how they use Teaching methods to teach sewing. The targeted respondent contacted to give assistance Consist of students from BICCES, fashion teachers and tailored garment makers. The sample size consisted of 5 teachers, 20 students and 5 tailors were selected to answer questionnaire items that were used to gather the data for the study. The study revealed that most teachers and students agreed to the fact that demonstration, teaching and learning materials had a positive attitude towards the students in learning sewing. The study recommends that there should be more mechanisms in place to serve as a guide. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=VOTEC" title="VOTEC">VOTEC</a>, <a href="https://publications.waset.org/abstracts/search?q=BECE" title=" BECE"> BECE</a>, <a href="https://publications.waset.org/abstracts/search?q=BICCES" title=" BICCES"> BICCES</a>, <a href="https://publications.waset.org/abstracts/search?q=SHS" title=" SHS"> SHS</a> </p> <a href="https://publications.waset.org/abstracts/168892/using-demonstration-method-of-teaching-sewing-to-improve-the-skills-of-form-3-fashion-designing-students-a-case-of-baworo-integrated-community-center-for-employable-skills-bicces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168892.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">74</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">47</span> Assessing the Feasibility of Commercial Meat Rabbit Production in the Kumasi Metropolis of Ghana</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nana%20Segu%20Acquaah-Harrison">Nana Segu Acquaah-Harrison</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20Osei%20Mensah"> James Osei Mensah</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Aidoo"> Richard Aidoo</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Amponsah"> David Amponsah</a>, <a href="https://publications.waset.org/abstracts/search?q=Amy%20Buah"> Amy Buah</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilbert%20Aboagye"> Gilbert Aboagye</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study aimed at assessing the feasibility of commercial meat rabbit production in the Kumasi Metropolis of Ghana. Structured and unstructured questionnaires were utilized in obtaining information from two hundred meat consumers and 15 meat rabbit farmers. Data were analyzed using Net Present Value (NPV), Internal Rate of Return (IRR), Benefit Cost Ratio (BCR)/Profitability Index (PI) technique, percentages and chi-square contingency test. The study found that the current demand for rabbit meat is low (36%). The desirable nutritional attributes of rabbit meat and other socio economic factors of meat consumers make the potential demand for rabbit meat high (69%). It was estimated that GH¢5,292 (approximately $ 2672) was needed as a start-up capital for a 40-doe unit meat rabbit farm in Kumasi Metropolis. The cost of breeding animals, housing and equipment formed 12.47%, 53.97% and 24.87% respectively of the initial estimated capital. A Net Present Value of GH¢ 5,910.75 (approximately $ 2984) was obtained at the end of the fifth year, with an internal rate return and profitability index of 70% and 1.12 respectively. The major constraints identified in meat rabbit production were low price of rabbit meat, shortage of fodder, pest and diseases, high cost of capital, high cost of operating materials and veterinary care. Based on the analysis, it was concluded that meat rabbit production is feasible in the Kumasi Metropolis of Ghana. The study recommends embarking on mass advertisement; farmer association and adapting to new technologies in the production process will help to enhance productivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=feasibility" title="feasibility">feasibility</a>, <a href="https://publications.waset.org/abstracts/search?q=commercial%20meat%20rabbit" title=" commercial meat rabbit"> commercial meat rabbit</a>, <a href="https://publications.waset.org/abstracts/search?q=production" title=" production"> production</a>, <a href="https://publications.waset.org/abstracts/search?q=Kumasi" title=" Kumasi"> Kumasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghana" title=" Ghana"> Ghana</a> </p> <a href="https://publications.waset.org/abstracts/110855/assessing-the-feasibility-of-commercial-meat-rabbit-production-in-the-kumasi-metropolis-of-ghana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110855.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">132</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> A Tale of Seven Districts: Reviewing The Past, Present and Future of Patent Litigation Filings to Form a Two-Step Burden-Shifting Framework for 28 U.S.C. § 1404(a)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Timothy%20T.%20Hsieh">Timothy T. Hsieh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Current patent venue transfer laws under 28 U.S.C. § 1404(a) e.g., the Gilbert factors from Gulf Oil Corp. v. Gilbert, 330 U.S. 501 (1947) are too malleable in that they often lead to frequent mandamus orders from the U.S. Court of Appeals for the Federal Circuit (“Federal Circuit”) overturning district court rulings on venue transfer motions. Thus, this paper proposes a more robust two-step burden-shifting framework that replaces the eight Gilbert factors. Moreover, a brief history of venue transfer patterns in the seven most active federal patent district courts is covered, with special focus devoted to the venue transfer orders from Judge Alan D Albright of the U.S. District Court for the Western District of Texas. A comprehensive data summary of 45 case sets where the Federal Circuit ruled on writs of mandamus involving Judge Albright’s transfer orders is subsequently provided, with coverage summaries of certain cases including four precedential ones from the Federal Circuit. This proposed two-step burden shifting framework is then applied to these venue transfer cases, as well as Federal Circuit mandamus orders ruling on those decisions. Finally, alternative approaches to remedying the frequent reversals for venue transfer will be discussed, including potential legislative solutions, adjustments to common law framework approaches to venue transfer, deference to the inherent powers of Article III U.S. District Judge, and a unified federal patent district court. Overall, this paper seeks to offer a more robust and consistent three-step burden-shifting framework for venue transfer and for the Federal Circuit to follow in administering mandamus orders, which might change somewhat in light of Western District of Texas Chief Judge Orlando Garcia’s order on redistributing Judge Albright’s patent cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patent%20law" title="Patent law">Patent law</a>, <a href="https://publications.waset.org/abstracts/search?q=venue" title=" venue"> venue</a>, <a href="https://publications.waset.org/abstracts/search?q=judge%20Alan%20Albright" title=" judge Alan Albright"> judge Alan Albright</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20contacts" title=" minimum contacts"> minimum contacts</a>, <a href="https://publications.waset.org/abstracts/search?q=western%20district%20of%20Texas" title=" western district of Texas"> western district of Texas</a> </p> <a href="https://publications.waset.org/abstracts/164755/a-tale-of-seven-districts-reviewing-the-past-present-and-future-of-patent-litigation-filings-to-form-a-two-step-burden-shifting-framework-for-28-usc-1404a" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164755.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">109</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> An Interdisciplinary Approach to Investigating Style: A Case Study of a Chinese Translation of Gilbert’s (2006) Eat Pray Love</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elaine%20Y.%20L.%20Ng">Elaine Y. L. Ng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Elizabeth Gilbert’s (2006) biography Eat, Pray, Love describes her travels to Italy, India, and Indonesia after a painful divorce. The author’s experiences with love, loss, search for happiness, and meaning have resonated with a huge readership. As regards the translation of Gilbert’s (2006) Eat, Pray, Love into Chinese, it was first translated by a Taiwanese translator He Pei-Hua and published in Taiwan in 2007 by Make Boluo Wenhua Chubanshe with the fairly catching title “Enjoy! Traveling Alone.” The same translation was translocated to China, republished in simplified Chinese characters by Shanxi Shifan Daxue Chubanshe in 2008 and renamed in China, entitled “To Be a Girl for the Whole Life.” Later on, the same translation in simplified Chinese characters was reprinted by Hunan Wenyi Chubanshe in 2013. This study employs Munday’s (2002) systemic model for descriptive translation studies to investigate the translation of Gilbert’s (2006) Eat, Pray, Love into Chinese by the Taiwanese translator Hu Pei-Hua. It employs an interdisciplinary approach, combining systemic functional linguistics and corpus stylistics with sociohistorical research within a descriptive framework to study the translator’s discursive presence in the text. The research consists of three phases. The first phase is to locate the target text within its socio-cultural context. The target-text context concerning the para-texts, readers’ responses, and the publishers’ orientation will be explored. The second phase is to compare the source text and the target text for the categorization of translation shifts by using the methodological tools of systemic functional linguistics and corpus stylistics. The investigation concerns the rendering of mental clauses and speech and thought presentation. The final phase is an explanation of the causes of translation shifts. The linguistic findings are related to the extra-textual information collected in an effort to ascertain the motivations behind the translator’s choices. There exist sets of possible factors that may have contributed to shaping the textual features of the given translation within a specific socio-cultural context. The study finds that the translator generally reproduces the mental clauses and speech and thought presentation closely according to the original. Nevertheless, the language of the translation has been widely criticized to be unidiomatic and stiff, losing the elegance of the original. In addition, the several Chinese translations of the given text produced by one Taiwanese and two Chinese publishers are basically the same. They are repackaged slightly differently, mainly with the change of the book cover and its captions for each version. By relating the textual findings to the extra-textual data of the study, it is argued that the popularity of the Chinese translation of Gilbert’s (2006) Eat, Pray, Love may not be attributed to the quality of the translation. Instead, it may have to do with the way the work is promoted strategically by the social media manipulated by the four e-bookstores promoting and selling the book online in China. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chinese%20translation%20of%20eat%20pray%20love" title="chinese translation of eat pray love">chinese translation of eat pray love</a>, <a href="https://publications.waset.org/abstracts/search?q=corpus%20stylistics" title=" corpus stylistics"> corpus stylistics</a>, <a href="https://publications.waset.org/abstracts/search?q=motivations%20for%20translation%20shifts" title=" motivations for translation shifts"> motivations for translation shifts</a>, <a href="https://publications.waset.org/abstracts/search?q=systemic%20approach%20to%20translation%20studies" title=" systemic approach to translation studies "> systemic approach to translation studies </a> </p> <a href="https://publications.waset.org/abstracts/87113/an-interdisciplinary-approach-to-investigating-style-a-case-study-of-a-chinese-translation-of-gilberts-2006-eat-pray-love" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87113.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">175</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> Learning about the Strengths and Weaknesses of Urban Climate Action Plans</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prince%20Dacosta%20Aboagye">Prince Dacosta Aboagye</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayyoob%20Sharifi"> Ayyoob Sharifi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cities respond to climate concerns mainly through their climate action plans (CAPs). A comprehensive content analysis of the dynamics in existing urban CAPs is not well represented in the literature. This literature void presents a difficulty in appreciating the strengths and weaknesses of urban CAPs. Here, we perform a qualitative content analysis (QCA) on CAPs from 278 cities worldwide and use text-mining tools to map and visualize the relevant data. Our analysis showed a decline in the number of CAPs developed and published following the global COVID-19 lockdown period. Evidently, megacities are leading the deep decarbonisation agenda. We also observed a transition from developing mainly mitigation-focused CAPs pre-COP21 to both mitigation and adaptation CAPs. A lack of inclusiveness in local climate planning was common among European and North American cities. The evidence is a catalyst for understanding the trends in existing urban CAPs to shape future urban climate planning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urban" title="urban">urban</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20action%20plans" title=" climate action plans"> climate action plans</a>, <a href="https://publications.waset.org/abstracts/search?q=strengths" title=" strengths"> strengths</a>, <a href="https://publications.waset.org/abstracts/search?q=weaknesses" title=" weaknesses"> weaknesses</a> </p> <a href="https://publications.waset.org/abstracts/161978/learning-about-the-strengths-and-weaknesses-of-urban-climate-action-plans" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161978.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">97</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Transformative Learning and the Development of Cultural Humility in Social Work Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruilin%20Zhu">Ruilin Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Olco%C5%84"> Katarzyna Olcoń</a>, <a href="https://publications.waset.org/abstracts/search?q=Rose%20M.%20Pulliam"> Rose M.

This study was carried out to examine effective non-medical related strategies patients use to cope and manage their SCD condition. Methods: SCD patients (387) consisting of 180 males and 204 females between 18-65 years old years participated in the study. A cross-sectional research design was used in which participants completed questionnaires on pain, non-medical coping and management strategies, anxiety, and depression. Results of multiple regression analysis showed that socio-demographic characteristics contributed to the variance in the pain associated with SCD. Results: Over 90% of participants reported that pains associated with SCD were the main reason for seeking treatment in SCD crisis. In terms of non-medical related coping strategies, attending a place of worship and praying were the main coping strategies used in SCD crises, suggesting that patients’ beliefs, particularly in a supernatural being, served as a mitigating factor in the process of coping with the pain associated with SCD crisis. Also, avoidance and withdrawal from people and social activities were reported to be strategies used to cope effectively with the pain associated with SCD crisis. Conclusion: This indicates that it is imperative to incorporate non-medical related coping and management strategies, especially religious beliefs and psychosocial factors, to coping and management of the pain associated with SCD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anxiety" title="anxiety">anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=depression" title=" depression"> depression</a>, <a href="https://publications.waset.org/abstracts/search?q=sickle%20cell%20disease" title=" sickle cell disease"> sickle cell disease</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=socio-demographic%20characteristics" title=" socio-demographic characteristics"> socio-demographic characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghana" title=" Ghana"> Ghana</a> </p> <a href="https://publications.waset.org/abstracts/47541/pain-management-strategies-for-effective-coping-with-sickle-cell-disease-the-perspective-of-patients-in-ghana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47541.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">410</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Photo-Thermal Degradation Analysis of Single Junction Amorphous Silicon Solar Module Eva Encapsulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gilbert%20O.%20Osayemwenre">Gilbert O.

Hotspot formation causes the EVA encapsulation to undergo photothermal deterioration and molecular breakdown by UV radiation. This leads to diffusion of chemical particles into other layers. During outdoor deployment, the EVA encapsulation in the affect region loses its adhesive strength, when this happen the affected region layer undergoes rapid delamination. The presence of photo-thermal degradation is detrimental to PV modules as it causes both optical and thermal degradation. Also, it enables the encapsulant to be more susceptible to chemicals substance and moisture. Our findings show a high concentration of Sodium, Phosphorus and Aluminium which originate from the glass substrate, cell emitter and back contact respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ethylene%20vinyl%20acetate%20%28EVA%29" title="ethylene vinyl acetate (EVA)">ethylene vinyl acetate (EVA)</a>, <a href="https://publications.waset.org/abstracts/search?q=encapsulation" title=" encapsulation"> encapsulation</a>, <a href="https://publications.waset.org/abstracts/search?q=photo-thermal%20degradation" title=" photo-thermal degradation"> photo-thermal degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=thermogravimetric%20analysis%20%28TGA%29" title=" thermogravimetric analysis (TGA)"> thermogravimetric analysis (TGA)</a>, <a href="https://publications.waset.org/abstracts/search?q=scanning%20probe%20microscope%20%28SPM%29" title=" scanning probe microscope (SPM)"> scanning probe microscope (SPM)</a> </p> <a href="https://publications.waset.org/abstracts/47891/photo-thermal-degradation-analysis-of-single-junction-amorphous-silicon-solar-module-eva-encapsulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47891.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">306</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Electrical Performance Analysis of Single Junction Amorphous Silicon Solar (a-Si:H) Modules Using IV Tracer (PVPM)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gilbert%20Omorodion%20Osayemwenre">Gilbert Omorodion Osayemwenre</a>, <a href="https://publications.waset.org/abstracts/search?q=Edson%20Meyer"> Edson Meyer</a>, <a href="https://publications.waset.org/abstracts/search?q=R.%20T.%20Taziwa"> R.

Like crystalline silicon PV modules, the electrical characterisation and performance of single junction amorphous silicon modules are best described by its current-voltage (IV) characteristic. However, IV curve has a direct dependence on the type of PV technology and material properties used. The analysis reveals discrepancies in the modules performance parameter even though they are of similar technology. The aim of this work is to compare the electrical performance output of each module, using electrical parameters with the aid of PVPM 100040C IV tracer.

With the goal to effectively simulate room-temperature loops for large iron-oxide based systems at relatively slow sweep rates on the order of 1 Oe/ns or less, a coarse-graining scheme is proposed and tested. The scheme is derived from a previously developed renormalization-group approach. Loops associated with nanorods, used as building blocks for larger nanoparticles that were employed in preclinical trials (Dennis et al., 2009 Nanotechnology 20 395103), serve as the model test system. The scaling algorithm is shown to produce nearly identical loops over several decades in the model grain sizes. Sweep-rate scaling involving the damping constant alpha is also demonstrated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coarse-graining" title="coarse-graining">coarse-graining</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperthermia" title=" hyperthermia"> hyperthermia</a>, <a href="https://publications.waset.org/abstracts/search?q=hysteresis%20loops" title=" hysteresis loops"> hysteresis loops</a>, <a href="https://publications.waset.org/abstracts/search?q=micromagnetic%20simulations" title=" micromagnetic simulations"> micromagnetic simulations</a> </p> <a href="https://publications.waset.org/abstracts/112852/coarse-graining-in-micromagnetic-simulations-of-magnetic-hyperthermia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112852.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">149</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Investigating the Dynamics of Knowledge Acquisition in Undergraduate Mathematics Students Using Differential Equations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gilbert%20Makanda">Gilbert Makanda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The problem of the teaching of mathematics is studied using differential equations. A mathematical model for knowledge acquisition in mathematics is developed. In this study we adopt the mathematical model that is normally used for disease modelling in the teaching of mathematics. It is assumed that teaching is 'infecting' students with knowledge thereby spreading this knowledge to the students. It is also assumed that students who gain this knowledge spread it to other students making disease model appropriate to adopt for this problem. The results of this study show that increasing recruitment rates, learning contact with teachers and learning materials improves the number of knowledgeable students. High dropout rates and forgetting taught concepts also negatively affect the number of knowledgeable students. The developed model is then solved using Matlab ODE45 and \verb"lsqnonlin" to estimate parameters for the actual data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=differential%20equations" title="differential equations">differential equations</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20acquisition" title=" knowledge acquisition"> knowledge acquisition</a>, <a href="https://publications.waset.org/abstracts/search?q=least%20squares" title=" least squares"> least squares</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamical%20systems" title=" dynamical systems"> dynamical systems</a> </p> <a href="https://publications.waset.org/abstracts/34955/investigating-the-dynamics-of-knowledge-acquisition-in-undergraduate-mathematics-students-using-differential-equations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34955.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">423</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Students Perceptions on the Relevance of High School Mathematics in University Education in South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gilbert%20Makanda">Gilbert Makanda</a>, <a href="https://publications.waset.org/abstracts/search?q=Roelf%20Sypkens"> Roelf Sypkens</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study we investigated the relevance of high school mathematics in university education. The paper particularly focused on whether the concepts taught in high school are enough for engineering courses at diploma level. The study identified particular concepts that are required in engineering courses whether they were adequately covered in high school. A questionnaire was used to investigate whether relevant topics were covered in high school. The respondents were 228 first year students at the Central University of Technology in the Faculty of Engineering and Information Technology. The study indicates that there are some topics such as integration, complex numbers and matrices that are not done at high schools and are required in engineering courses at university. It is further observed that some students did not cover the topics that are in the current syllabus. Female students enter the university less prepared than their male counterparts.

The receiver front-end comprises a wideband low-noise amplifier (LNA), and a double-balanced Gilbert cell mixer with a current-reused RF single-to-differential (STD) converter, an LO Marchand balun and a baseband amplifier. The receiver front-end consumes 34.4 mW and achieves LO-RF isolation of 60.7 dB, LO-IF isolation of 45.3 dB and RF-IF isolation of 41.9 dB at RF of 60 GHz and LO of 59.9 GHz. At IF of 0.1 GHz, the receiver front-end achieves maximum conversion gain (CG) of 26.1 dB at RF of 64 GHz and CG of 25.2 dB at RF of 60 GHz. The corresponding 3-dB bandwidth of RF is 7.3 GHz (58.4 GHz to 65.7 GHz). The measured minimum noise figure was 5.6 dB at 64 GHz, one of the best results ever reported for a 60 GHz CMOS receiver front-end. In addition, the measured input 1-dB compression point and input third-order inter-modulation point are -33.1 dBm and -23.3 dBm, respectively, at 60 GHz. These results demonstrate the proposed receiver front-end architecture is very promising for 60 GHz direct-conversion transceiver applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CMOS" title="CMOS">CMOS</a>, <a href="https://publications.waset.org/abstracts/search?q=60%20GHz" title=" 60 GHz"> 60 GHz</a>, <a href="https://publications.waset.org/abstracts/search?q=direct-conversion%20transceiver" title=" direct-conversion transceiver"> direct-conversion transceiver</a>, <a href="https://publications.waset.org/abstracts/search?q=LNA" title=" LNA"> LNA</a>, <a href="https://publications.waset.org/abstracts/search?q=down-conversion%20mixer" title=" down-conversion mixer"> down-conversion mixer</a>, <a href="https://publications.waset.org/abstracts/search?q=marchand%20balun" title=" marchand balun"> marchand balun</a>, <a href="https://publications.waset.org/abstracts/search?q=current-reused" title=" current-reused"> current-reused</a> </p> <a href="https://publications.waset.org/abstracts/32604/a-low-power-low-noise-and-high-gain-5866-ghz-cmos-receiver-front-end-for-short-range-high-speed-wireless-communications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32604.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">452</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Risk Prioritization in Tunneling Construction Projects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Nantes">David Nantes</a>, <a href="https://publications.waset.org/abstracts/search?q=George%20Gilbert"> George Gilbert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are a lot of risks that might crop up as a tunneling project develops, and it's crucial to be aware of them. Due to the unexpected nature of tunneling projects and the interconnectedness of risk occurrences, the risk assessment approach presents a significant challenge. The purpose of this study is to provide a hybrid FDEMATEL-ANP model to help prioritize risks during tunnel construction projects. The ambiguity in expert judgments and the relative severity of interdependencies across risk occurrences are both taken into consideration by this model, thanks to the Fuzzy Decision-Making Trial and Evaluation Laboratory (FDEMATEL). The Analytic Network Process (ANP) method is used to rank priorities and assess project risks. The authors provide a case study of a subway tunneling construction project to back up the validity of their methodology. The results showed that the proposed method successfully isolated key risk factors and elucidated their interplay in the case study.

By synthesizing research from dynamical systems theory, psychology, and computational neuroscience, the review provides an overview of the current understanding of ANN function in memory formation, reinforcement, retrieval, and forgetting. Key mathematical foundations, including dynamical systems theory and energy functions, are discussed to explain the behavior and stability of these networks. The review also examines empirical applications of ANNs in cognitive processes such as semantic memory and episodic recall, as well as highlighting the hippocampus's role in pattern separation and completion. The review addresses challenges like catastrophic forgetting and noise effects on memory retrieval. By identifying gaps between theoretical models and empirical findings, it highlights the interdisciplinary nature of ANN research and suggests future exploration areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attractor%20neural%20networks" title="attractor neural networks">attractor neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=connectionism" title=" connectionism"> connectionism</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20modeling" title=" computational modeling"> computational modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20neuroscience" title=" cognitive neuroscience"> cognitive neuroscience</a> </p> <a href="https://publications.waset.org/abstracts/188973/a-review-of-attractor-neural-networks-and-their-use-in-cognitive-science" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188973.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">28</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Assessing Knowledge and Compliance of Motor Riders on Road Safety Regulations in Hohoe Municipality of Ghana: A Cross-Sectional Quantitative Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matthew%20Venunye%20Fianu">Matthew Venunye Fianu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jerry%20Fiave"> Jerry Fiave</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebenezer%20Kye-Mensah"> Ebenezer Kye-Mensah</a>, <a href="https://publications.waset.org/abstracts/search?q=Dacosta%20Aboagye"> Dacosta Aboagye</a>, <a href="https://publications.waset.org/abstracts/search?q=Felix%20Osei-Sarpong"> Felix Osei-Sarpong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Road traffic accidents involving motorbikes are a priority public health concern in Ghana. While there are local initiatives to address this public health challenge, little is known about motor riders’ knowledge and compliance with road safety regulations (RSR) and their association with RTAs. The aim of this study was, therefore, to assess motorbike riders’ knowledge and compliance with RSRs. Methodology: Motorbike riders in Hohoe Municipality were randomly sampled in a cross-sectional study in June 2022. Data were collected from 237 riders using a questionnaire designed in Kobocollect and administered by ten research assistants. A score of 70% or less is considered low for knowledge and compliance. The data were exported into Excel and imported into STATA 17 for analysis. A chi-square test was performed to generate descriptive and inferential statistics to establish the association between independent and dependent variables. Results: All 237 respondents were male, and each of them completed the questionnaire representing a 100% response rate. Participants who had knowledge about speed limit at different segments of the road were 59(24.9%), the use of helmet were 124 (52.3%), and alcohol use were 152 (64.1%). Participants who complied with regulations on speed limits, helmet use, and alcohol use were 108 (45.6%), 179(75.5%), and 168(70.8%), respectively. Riders who had at least junior high school education were 2.43 times more likely to adhere to RSR [cOR =2.43(95%CI= 1.15-6.33) p= 0.023] than those who had less education. Similarly, riders who had high knowledge about RSR were 2.07 times more likely to comply with RSR than those who had less knowledge [AOR= -2.07 (95% CI= 0.34-0.97), p=0.038]. Conclusion: Motor riders in the Hohoe Municipality had low knowledge as well as low compliance with road safety regulations. This could be a contributor to road traffic accidents. It is therefore recommended that road safety regulatory authorities and relevant stakeholders enhance the enforcement of RSR. There should also be country-specific efforts to increase awareness among all motor riders, especially those with less than junior high school education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compliance" title="compliance">compliance</a>, <a href="https://publications.waset.org/abstracts/search?q=motor%20riders" title=" motor riders"> motor riders</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20safety%20regulations" title=" road safety regulations"> road safety regulations</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20traffic%20accident" title=" road traffic accident"> road traffic accident</a> </p> <a href="https://publications.waset.org/abstracts/163530/assessing-knowledge-and-compliance-of-motor-riders-on-road-safety-regulations-in-hohoe-municipality-of-ghana-a-cross-sectional-quantitative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163530.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> An Enhanced AODV Routing Protocol for Wireless Sensor and Actuator Networks </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Apidet%20Booranawong">Apidet Booranawong</a>, <a href="https://publications.waset.org/abstracts/search?q=Wiklom%20Teerapabkajorndet"> Wiklom Teerapabkajorndet</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An enhanced ad-hoc on-demand distance vector routing (E-AODV) protocol for control system applications in wireless sensor and actuator networks (WSANs) is proposed. Our routing algorithm is designed by considering both wireless network communication and the control system aspects. Control system error and network delay are the main selection criteria in our routing protocol. The control and communication performance is evaluated on multi-hop IEEE 802.15.4 networks for building-temperature control systems. The Gilbert-Elliott error model is employed to simulate packet loss in wireless networks. The simulation results demonstrate that the E-AODV routing approach can significantly improve the communication performance better than an original AODV routing under various packet loss rates.

Therefore, the objective of this study was to assess the quality characteristics of selected locally produced and marketed soft drinks. Three (3) different batches of 23 soft drinks were sampled from the Takoradi markets. The samples were prescreened for the presence of reducing sugars, phosphates, alcohol and carbon dioxide. The heavy metal contents and physicochemical properties were also determined with AOAC methods. The results indicated the presence of reducing sugars, carbon dioxide and the absence of alcohol in all the selected soft drink samples. The pH, total sugars, moisture, total soluble solids (TSS) and titratable acidity ranged from 2.42 – 3.44, 3.30 – 10.44%, 85.63 – 94.85%, 5.00 – 13.33°Brix, and 0.21 – 1.99% respectively. The concentration of heavy metals were also below detection limits in all samples. The quality of the selected were within specifications prescribed by regulatory bodies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal%20contamination" title="heavy metal contamination">heavy metal contamination</a>, <a href="https://publications.waset.org/abstracts/search?q=locally%20manufactured" title=" locally manufactured"> locally manufactured</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20drinks" title=" soft drinks"> soft drinks</a> </p> <a href="https://publications.waset.org/abstracts/124288/quality-assessment-of-some-selected-locally-produced-and-marketed-soft-drinks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124288.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Empirical Analytical Modelling of Average Bond Stress and Anchorage of Tensile Bars in Reinforced Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maruful%20H.%20Mazumder">Maruful H.

Non-destructive evaluation, based on ultrasonics, of the dynamic mechanical properties of the materials including elastic, shear and bulk modulus as well as Poisson’s ratio showed optimum property improvement at 0.5 %wt tube loading while evidence of nanoscale-specific energy dissipative characteristics acting complementary to nanotube bridging and pull-out indicate a high potential in a wide range of reinforcing and multifunctional applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ceramic%20matrix%20composites" title="ceramic matrix composites">ceramic matrix composites</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotubes" title=" carbon nanotubes"> carbon nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=toughening" title=" toughening"> toughening</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonics" title=" ultrasonics "> ultrasonics </a> </p> <a href="https://publications.waset.org/abstracts/32657/new-highly-scalable-carbon-nanotube-reinforced-glasses-and-ceramics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32657.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">374</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> CFD Simulation and Investigation of Critical Two-Phase Flow Rate in Wellhead Choke</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Rafie%20Boldaji">Alireza Rafie Boldaji</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Saboonchi"> Ahmad Saboonchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chokes are commonly used in oil and gas production systems. A choke is a restriction basically designed to control flow rates of oil and gas wells, to prevent the downstream disturbances from propagating upstream (critical flow), and to protect the surface equipment facilities against slugging at high flowing pressures. There are different methods to calculate the multiphase flow rate, one of the multiphase flow measurement methods is the separation and measurement by on¬e-phaseFlow meter, another common method is the use of movable separator, their operations are very labor-intensive and costly. The current method used is based on the flow differential pressure on both sides of choke. Three groups of correlations describing two-phase flow through wellhead chokes were examined. The first group involved simple empirical equations similar to those of Gilbert, the second group comprised derived equations of two-phase flow incorporating PVT properties, and third group is computational method. In the article we calculate the flow of oil and gas through choke with simulation of this two phase flow bye computational fluid dynamic method, we use Ansys- fluent for this simulation and finally compared results of computational simulation whit empirical equations, the results show good agreement between experimental and numerical results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=two-phase" title=" two-phase"> two-phase</a>, <a href="https://publications.waset.org/abstracts/search?q=choke" title=" choke"> choke</a>, <a href="https://publications.waset.org/abstracts/search?q=critical" title=" critical"> critical</a> </p> <a href="https://publications.waset.org/abstracts/39745/cfd-simulation-and-investigation-of-critical-two-phase-flow-rate-in-wellhead-choke" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39745.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">277</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Investigating the Dynamics of Knowledge Acquisition in Learning Using Differential Equations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gilbert%20Makanda">Gilbert Makanda</a>, <a href="https://publications.waset.org/abstracts/search?q=Roelf%20Sypkens"> Roelf Sypkens</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A mathematical model for knowledge acquisition in teaching and learning is proposed.

The study also investigates effect of individual interaction and learning from other sources to facilitate learning. The study fits actual data to a general mathematical model using Matlab ODE45 and lsqnonlin to obtain a unique mathematical model that can be used to predict knowledge acquisition. The data used in this study was obtained from the tutorial test results for mathematics 2 students from the Central University of Technology, Free State, South Africa in the department of Mathematical and Physical Sciences. The study confirms already known results that increasing dropout rates and forgetting taught concepts reduce the population of knowledgeable students. Increasing teaching contacts and access to other learning materials facilitate knowledge acquisition. The effect of increasing dropout rates is more enhanced in the later stages of learning than earlier stages.

Propounded by Noam Chomsky in 1965, the theory transforms sentences from an active structure to a passive one by the application of established rules of the theory. Resident in the body of syntax, the rules include movement, insertion, substitution, and deletion rules. Using the movement rule, the analysis is armed with the qualitative research method, on which the works of scholars were duly consulted for more insight and in line with the academic practice in research activities. The investigation showed that the rules of competent grammar explain the formulation of sentences in a language and how transformation takes place among sentences from a deep structure to a surface structure with accurate results. The structural differences that could be got through dative movement and the deletion of the preposition; passivisation got from an active sentence by the insertion of the preposition “by” a “be verb” and the aspect tense marker “–en”, held as the creative aspect of language vocabulary and the subject-auxiliary inversion that exchanges the auxiliary of a sentence with the subject of the same sentence thereby transforming a kennel sentence to a polar question, viewed as an external argument under θ-theory. Generativism in language design, therefore, changes available types of sentences and relates one form of linguistic category with others in language design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=language" title="language">language</a>, <a href="https://publications.waset.org/abstracts/search?q=generate" title=" generate"> generate</a>, <a href="https://publications.waset.org/abstracts/search?q=transformation" title=" transformation"> transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=structure" title=" structure"> structure</a>, <a href="https://publications.waset.org/abstracts/search?q=design" title=" design"> design</a> </p> <a href="https://publications.waset.org/abstracts/180413/generativism-in-language-design-and-their-effects-on-string-of-constructions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/180413.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">68</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Network and Sentiment Analysis of U.S. Congressional Tweets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chaitanya%20Kanakamedala">Chaitanya Kanakamedala</a>, <a href="https://publications.waset.org/abstracts/search?q=Hansa%20Pradhan"> Hansa Pradhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Carter%20Gilbert"> Carter Gilbert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Social media platforms, such as Twitter, are excellent datasets for understanding human interactions and sentiments. This report explores social dynamics among US Congressional members through a network analysis applied to a dataset of tweets spanning 2008 to 2017 from the ’US Congressional Tweets Dataset’. In this report, we preform network analysis where connections between users (edges) are established based on a similarity threshold: two tweets are connected if the tweets they post are similar. By utilizing the Natural Language Toolkit (NLTK) and NetworkX, we quantified tweet similarity and constructed a graph comprising various interconnected components. Each component represents a cluster of users with closely aligned content. We then preform sentiment analysis on each cluster to explore the prevalent emotions and opinions within these groups. Our findings reveal that despite the initial expectation of distinct ideological divisions typically aligning with party lines, the analysis exposed a high degree of topical convergence across tweets from different political affiliations. The analysis preformed in this report not only highlights the potential of social media as a tool for political communication but also suggests a complex layer of interaction that transcends traditional partisan boundaries, reflecting a complicated landscape of politics in the digital age. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=natural%20language%20processing" title="natural language processing">natural language processing</a>, <a href="https://publications.waset.org/abstracts/search?q=sentiment%20analysis" title=" sentiment analysis"> sentiment analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=centrality%20analysis" title=" centrality analysis"> centrality analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=topic%20modeling" title=" topic modeling"> topic modeling</a> </p> <a href="https://publications.waset.org/abstracts/189004/network-and-sentiment-analysis-of-us-congressional-tweets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189004.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">33</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Design and Implementation of a 94 GHz CMOS Double-Balanced Up-Conversion Mixer for 94 GHz Imaging Radar Sensors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yo-Sheng%20Lin">Yo-Sheng Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Run-Chi%20Liu"> Run-Chi Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chien-Chu%20Ji"> Chien-Chu Ji</a>, <a href="https://publications.waset.org/abstracts/search?q=Chih-Chung%20Chen"> Chih-Chung Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Chien-Chin%20Wang"> Chien-Chin Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A W-band double-balanced mixer for direct up-conversion using standard 90 nm CMOS technology is reported. The mixer comprises an enhanced double-balanced Gilbert cell with PMOS negative resistance compensation for conversion gain (CG) enhancement and current injection for power consumption reduction and linearity improvement, a Marchand balun for converting the single LO input signal to differential signal, another Marchand balun for converting the differential RF output signal to single signal, and an output buffer amplifier for loading effect suppression, power consumption reduction and CG enhancement. The mixer consumes low power of 6.9 mW and achieves LO-port input reflection coefficient of -17.8~ -38.7 dB and RF-port input reflection coefficient of -16.8~ -27.9 dB for frequencies of 90~100 GHz. The mixer achieves maximum CG of 3.6 dB at 95 GHz, and CG of 2.1±1.5 dB for frequencies of 91.9~99.4 GHz. That is, the corresponding 3 dB CG bandwidth is 7.5 GHz. In addition, the mixer achieves LO-RF isolation of 36.8 dB at 94 GHz. To the authors’ knowledge, the CG, LO-RF isolation and power dissipation results are the best data ever reported for a 94 GHz CMOS/BiCMOS up-conversion mixer. <p
