An exact evaluation of the Casimir energy in two planar models

The method of images is used to calculate the Casimir energy in Euclidean space with Dirichlet boundary conditions for two planar models, namely: i. the non-relativistic Landau problem for a charged particle of mass m for which - irrespective of the sign of the charge - the energy is negative, and ii. the model of a real, massive, noninteracting relativistic scalar field theory in 2 + 1 dimensions, for which the Casimir energy density is non-negative and is expressed in terms of the Lerch transcendent xxx and the polylogarithm xxx with 0 < xxx < 1 and n = 2, 3.Comment: 5 pages, 2 figures,IMFP2009 conference,to appear in forthcoming AIP Conf.Proc.1150 Request:There are three mathematical symbols denoted by xxx in the abstract below which are otherwise present in the abstract of the submission.Could you please include them so that the abstract below is complet

Software for end-of-life disassembly analysis

In recent years, many countries have developed legislations which are aimed to force manufacturers to recycle their products at the end of their life. However, before end-of-life products can be recycled, end-of-life disassembly needs to be in place. It entails large amounts of capital expenditure and time. Besides this, product designers also do not have experience in disassembling and recycling to determine the impact of various design aspects on difficulty at the disassembly stage. Therefore, there is a need for a tool to analyse the disassemblability and recyclability. This paper proposes software named as EDAS to fulfil those needs

Women and Politics in Kuwait

On May 17, 2008, Kuwait conducted its Twelfth election of its National Assembly. The most remarkable aspect of the election was the active participation of women, who gained their right to vote in May 2005. This paper argues that the main impediment for women’s inability to win any seat in the 11th and 12th Assemblies is their failure to work with each other and support their political rights. The objective of this article is to examine the Kuwaiti women’s struggle for political rights, their participation in the last two elections and investigate their inability to win any seats, in spite of the conduciveness of the political environment to their electoral success

Women and the Kuwaiti National Assembly

Kuwaiti women’s long struggle for a seat in the National Assembly culminated with remarkable success on May 16, 2009. For the very first time in Kuwait’s political history, the women’s movement managed to send four female representatives to the National Assembly. Their electoral success ushers a new phase in Kuwait’s political process in which women finally become active participants. The goal of this article is to examine women’s struggle for political rights, their electoral success, their role in current Kuwaiti politics, their accomplishments, and their future in politics in Kuwait

Arab Spring and Women in Kuwait

The Arab Spring, a revolutionary wave of protests and rebellions, and a process of regime change and democratization is sweeping the Arab world, but marginally touching women’s issues in Kuwait. While Arab women in Tunisia, Libya, Egypt, Morocco, Yemen, Jordan, and Syria are active participants and co-beneficiaries of the process of change, Kuwaiti women have lost their electoral gains made in 2009 in the latest elections held in February of 2012. The objective of this paper is to examine the impact of Arab Spring on women in Kuwait, and their continued struggle for political participation in the country. It will also highlight the accomplishments of the women’s movement and its inability to utilize the general atmosphere supportive of women’s rights in Kuwait to maintain its parliamentary representation in the Kuwaiti National Assembly

Penggunaan Bahan Pengisi (Filler) Serbuk Keramik, Ditinjau dari Parameter Marshall pada Lapis Aspal Beton (Laston)

Transportasi merupakan salah satu urat nadi dalam perkembangan kemajuan suatu daerah atau negara, salah satu prasarana transportasi darat yang sangat penting adalah jalan raya. Pada Kenyataannya masih banyak jalan-jalan yang kurang memenuhi syarat, sehingga banyak jalan rusak dikarenakan kurang mampu untuk menahan beban lalu lintas jalan dan menerima beban kendaraan yang berlebihan, oleh karena itu diperlukan alternatif campuran-beraspal yang dapat diterapkan agar mampu mengatasi kerusakan-kerusakan akibat melemahnya daya ikat aspal terhadap butiran agregat dan filler, baik karena suhu, cuaca, mutu aspal dan agregat, maupun metode pelaksanaan dilapangan. Salah satu cara untuk mengatasi hal tersebut adalah dengan menggunakan bahan filler alternatif yaitu dengan menggunakan serbuk keramik. Tujuan penelitian ini adalah: (1) Mengetahui sifat dan karakteristik aspal tanpa menggunakan serbuk keramik; (2) Mengetahui penggunaan serbuk keramik sebagai filler dengan kadar 0%, 20%, 40%, 60%, 80%, 100%. (3) mengetahui Pada kadar prosentase berapakah nilai optimum penggunaan serbuk keramik sebagai filler terhadap karakteristik parameter marshall pada campuran aspal beton. Dalam penelitian ini metode penelitian dibagi menjadi tiga tahapan yaitu tahapan pemilihan bahan, tahapan persiapan dan pembuatan benda uji, serta tahapan penelitian dan analisis data. Hasil dari penelitian menyebutkan bahwa: (1) Nilai Stabilitas, Flow, VIM, dan Marshall Quotient tanpa penambahan serbuk keramik sebagai filler akan terus meningkat sampai titik maksimum kemudian turun kesuatu nilai seiring penambahan serbuk keramik sebagai filler, (2) Dengan bertambahnya kadar serbuk keramik maka nilai Stabilitas dan nilai Marshall Quotient campuran aspal akan semakin tinggi. Dari uji statistik menunjukan bahwa ada perbedaan nilai stabilitas dan nilai Marshall Quotient pada Lapisan Aspal Beton yang signifikan pada kadar serbuk keramik 60%, 80%, 100%; Selain itu nilai flow, VIM, dan VMA mengalami peningkatan dan pada kadar optimum mengalami penururan seiring penambahan filler serbuk keramik. (3) semua nilai dari karakteristik parameter Marshall masuk dalam spesifikasi yang disyaratkan. Namun jika dilihat dari pengujian hipotesis menggunakan Software SPSS 16.0 for Windows ada dua nilai parameter Marshall yang memiliki perbedaan yang signifikan yaitu pada nilai stabilitas dan nilai Marshall Quotient yang memiliki nilai signifikansi 0,00 pada kadar prosentase 60%, 80%, dan 100%
