Therefore, in this work, PLA based polyurethane films were prepared by synthesizing with different types of isocyanates; methylene diisocyanate (MDI) and hexamethylene diisocyanates (HDI). For this purpose, PLA based polyurethane must have good strength and flexibility. Therefore, polycaprolactone which has better flexibility were prepared with PLA. An effective way to endow polylactic acid with toughness is through chain-extension reaction of the polylactic acid pre-polymer with polycaprolactone used as chain extender. Polyurethane prepared from MDI showed brittle behaviour, while, polyurethane prepared from HDI showed flexibility at same concentrations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodegradable%20polymer" title="biodegradable polymer">biodegradable polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible" title=" flexible"> flexible</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28lactic%20acid%29" title=" poly(lactic acid)"> poly(lactic acid)</a>, <a href="https://publications.waset.org/abstracts/search?q=polyurethane" title=" polyurethane"> polyurethane</a> </p> <a href="https://publications.waset.org/abstracts/7819/polylactic-acid-based-flexible-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7819.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">351</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">104</span> Event Extraction, Analysis, and Event Linking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anam%20Alam">Anam Alam</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahim%20Jamaluddin%20Kanji"> Rahim Jamaluddin Kanji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the rapid growth of event in everywhere, event extraction has now become an important matter to retrieve the information from the unstructured data.

The university examination timetabling problem (UETP), which involves assigning a set number of exams into a set number of timeslots whilst fulfilling all required conditions, has been widely investigated. The limitation of available timeslots and resources with the increasing number of examinations are the main reasons in the difficulty of solving this problem. Dynamical change in the examination scheduling system adds up the complication particularly in coping up with the demand and new requirements by the communities. Our objective is to investigate these demands and requirements with subjects taken from Universiti Malaysia Terengganu (UMT), through questionnaires. Integer linear programming model which reflects the preferences obtained to produce an effective examination timetabling was formed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=demands" title="demands">demands</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20timetabling" title=" educational timetabling"> educational timetabling</a>, <a href="https://publications.waset.org/abstracts/search?q=integer%20linear%20programming" title=" integer linear programming"> integer linear programming</a>, <a href="https://publications.waset.org/abstracts/search?q=scheduling" title=" scheduling"> scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=university%20examination%20timetabling%20problem%20%28UETP%29" title=" university examination timetabling problem (UETP)"> university examination timetabling problem (UETP)</a> </p> <a href="https://publications.waset.org/abstracts/49545/timetabling-communities-demands-for-an-effective-examination-timetabling-using-integer-linear-programming" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49545.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">337</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">101</span> The Introduction of Medicine Plants in Bogor Agricultural University: A Case Study in Cikabayan and Tropical Medicinal Plant Conservation Laboratory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eki%20Devung">Eki Devung</a>, <a href="https://publications.waset.org/abstracts/search?q=Eka%20Tyastutik"> Eka Tyastutik</a>, <a href="https://publications.waset.org/abstracts/search?q=Indha%20Annisa"> Indha Annisa</a>, <a href="https://publications.waset.org/abstracts/search?q=Digdaya%20Anoraga"> Digdaya Anoraga</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamaluddin%20Arsyad"> Jamaluddin Arsyad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plant medicine is a whole species of plants are known to have medicinal properties.

Making phone calls, instant messaging, playing online games and accessing the Internet are among the features added to a mobile phone, attracting teenagers to spend more hours fixated on their gadgets. As such, this study attempted to examine the frequency of time spent on mobile phones and how this influenced academic performance. A quantitative methodology was applied in this study, where face to face survey through the distribution of questionnaires was facilitated onto a group of 200 secondary school students from the Shah Alam community in Selangor,Malaysia. Both genders, male and females were assessed equally to find out if there exists a correlation between genders when measuring higher or lower frequency of attachment to mobile phones. It can also be seen that 100% correspondents have a mobile phone in their possession. The adolescents uses mobile phones daily, which shows students being somewhat addicted, as they tend to feel that it is necessary to use a mobile phone. The main findings of this research found out that, students that are mobile phone addictive received a lower grade in schools. Mobile phone addiction does affect academic performance negatively. As this study discusses the modern-day phenomenon, it is hoped that the findings and discussion could add to present literary works and help future researchers understand the relationship between mobile phone addiction and academic performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20performance" title="academic performance">academic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20phone%20addiction" title=" mobile phone addiction"> mobile phone addiction</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a>, <a href="https://publications.waset.org/abstracts/search?q=student" title=" student "> student </a> </p> <a href="https://publications.waset.org/abstracts/93790/the-influence-of-mobile-phone-addiction-on-academic-performance-among-teenagers-in-shah-alam-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93790.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">346</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">84</span> Isolation and Characterization of Collagen from Chicken Feet</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Hashim">P.

Chemical composition and characteristics of chicken feet collagen such as amino acid composition, SDS-PAGE patterns, FTIR spectra and thermal properties were evaluated. The chicken feet collagen is rich in the amino acids glycine, glutamic acid, proline and hydroxyproline. Electrophoresis pattern demonstrated two distinct α-chains (α1 and α2) and β chain, indicating that type I collagen is a major component of chicken feet collagen. The thermal stability of collagen isolated by papain and pepsin revealed stable denaturation temperatures of 48.40 and 53.35°C, respectively. The FTIR spectra of both collagens were similar with amide regions in A, B, I, II, and III.

One of proposed solutions by Internet Engineering Task Force (IETF) is to connect the local, multi-hop, and infrastructure-less Mobile Ad hoc Network (MANET) with Internet structure. This connection is done through multi-interface devices known as Internet Gateways. Many issues are related to this connection like gateway discovery, hand off, address auto-configuration and selecting the optimum gateway when multiple gateways exist. Many studies were done proposing gateway selection schemes with a single selection criterion or weighted multiple criteria.

HPDLCs are modeled as a mixture of polymer and liquid crystals (LCs) that categorized as an anisotropic medium. FDTD method is directly solves Maxwell’s equation with less approximation, so this method can analyze more flexible and general approach for the arbitrary anisotropic media. As the results from FDTD simulation, the highest diffraction efficiency occurred at ±19 degrees (Bragg angle) using p polarization incident beam to Bragg grating, Q > 10 when the pitch is 1µm. Therefore, the liquid crystal is assumed to be aligned parallel to the grating constant vector during these parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=birefringence" title="birefringence">birefringence</a>, <a href="https://publications.waset.org/abstracts/search?q=diffraction%20efficiency" title=" diffraction efficiency"> diffraction efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20domain%20time%20difference" title=" finite domain time difference"> finite domain time difference</a>, <a href="https://publications.waset.org/abstracts/search?q=nematic%20liquid%20crystals" title=" nematic liquid crystals"> nematic liquid crystals</a> </p> <a href="https://publications.waset.org/abstracts/36230/analytical-study-of-holographic-polymer-dispersed-liquid-crystals-using-finite-difference-time-domain-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36230.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">460</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">80</span> Efficient Position Based Operation Code Authentication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hashim%20Ali">Hashim Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheheryar%20Khan"> Sheheryar Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Security for applications is always been a keen issue of concern. In general, security is to allow access of grant to legal user or to deny non-authorized access to the system. Shoulder surfing is an observation technique to hack an account or to enter into a system. When a malicious observer is capturing or recording the fingers of a user while he is entering sensitive inputs (PIN, Passwords etc.) and may be able to observe user’s password credential. It is very rigorous for a novice user to prevent himself from shoulder surfing or unaided observer in a public place while accessing his account. In order to secure the user account, there are five factors of authentication; they are: “(i) something you have, (ii) something you are, (iii) something you know, (iv) somebody you know, (v) something you process”. A technique has been developed of fifth-factor authentication “something you process” to provide novel approach to the user. In this paper, we have applied position based operational code authentication in such a way to more easy and user friendly to the user. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shoulder%20surfing" title="shoulder surfing">shoulder surfing</a>, <a href="https://publications.waset.org/abstracts/search?q=malicious%20observer" title=" malicious observer"> malicious observer</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitive%20inputs" title=" sensitive inputs"> sensitive inputs</a>, <a href="https://publications.waset.org/abstracts/search?q=authentication" title=" authentication"> authentication</a> </p> <a href="https://publications.waset.org/abstracts/14935/efficient-position-based-operation-code-authentication" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14935.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">272</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">79</span> Fracture Toughness Properties and FTIR Analysis of Corn Fiber Green Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Hashim">Ahmed Hashim</a>, <a href="https://publications.waset.org/abstracts/search?q=Aseel%20Abdullah"> Aseel Abdullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, the fracture toughness of new green composite based on bio-PMMA resin reinforced with randomly short corn natural fiber of constant weight fraction by 10% wt was investigated. The corn fiber surface was modified by mercerization treatment with two different concentrations of sodium hydroxide (3, and 5% NaOH) for 1.5 and 3 hours respectively. The effect of mercerization treatment on the fracture behavior of the green composites was analyzed by FTIR spectra. NaOH concentration of 3% for 1.5 hrs. That was used for corn fiber green composite should the highest improvement in terms of plane strain fracture toughness KIC which increased by 62 % compared to untreated fiber composite material. On the other hand, increased both concentrations of alkali solution to 5% NaOH and time of soaking to 3 hrs. reduced the values of KIC lower than the value of the unfilled material. <p
