Using Local Search with adaptive operator selection to solve the Progressive Party Problem

This paper investigates the use of adaptive operator selection in the context of Local Search to solve a constraint satisfaction problem, namely the Progressive Party Problem. Operators are selected according to a utility value which is computed, for each operator, from the solution quality and from the distance of the candidate solution to recently visited solutions in the search trajectory. We show that using several non-problem-specific operators gives comparable successful resolution rates to an algorithm customized for the problem, albeit with slower run times

Some larval morphological characteristics of Camelostrongylus mentulatus and Nematodirus spathiger

Monitoring of gastrointestinal nematode parasites in ruminants (domestic and wild) is often based on fecal examination techniques, looking for excreted eggs and larval forms using morphological keys. These, are more available in domestic ruminants, in which helminths are widely studied, than in wild ruminants.  This study tried to provide certain morphological elements that will help to recognize the L3 larvae of Camelostrongylus mentulatus and Nematodirus spathiger that could parasite either domestic or wild ruminants. For that, we resorted first to the culture of L3 larvae from fecal samples taken from African antelopes, and second by the microscopic characterization of each isolated larval morphological pattern previously identified by sequencing of its internal transcribed spacer (ITS-2) regions of the ribosomal DNA. The results of different microscopic captured images showed that Camelostrongylus mentulatus larva is 16 intestinal cells that measuring approximately 820 µm length, ‎≈ 25 µm wide, and ‎≈ 47 µm for its sheath tail extension and by this be closer to Teladorsagia circumcincta characteristics.  For Nematodirus spathiger, it possesses 8 gut cells and measuring about 1020 µm long, ‎≈ 25 µm wide, and‎ ≈ 143 µm for its sheath tail extension with specific tail appendages. Have done this, we were able to get some clarifications on the morphology of the studied larvae, and we believe thus that this study will contribute to the establishment of morphological identification keys especially for parasitic nematodes of wild ruminants

A strategic approach to the implementation and adoption of an e-government system for the ministry of education in Kuwait

E-government has recently fallen under the spotlight, having become a focus of government efforts in several countries around the world. The successful implementation of e-government is beset by many challenges such as social, political and technological considerations. All of these need to be given due care and attention for e-government to be successfully developed. Furthermore, in terms of adoption and uptake, e-government services still have some way to go, before it can be generally accepted in the public domain as a tool for accessing online services; this is clear given this technology is still in its embryonic stages. In addition, most of the previous studies have sought to understand the issues pertaining to implementation and adoption, however these studies have examined each factor in isolation respectively. And a small amount of research studies has focused on the factors which can impact e-government implementation and adoption using well-founded theoretical models or structures. In order to discuss and consider this technology, this thesis will present a conceptual framework based on two models, namely the Unified Theory of Acceptance and Use of Technology (UTAUT) (adoption) and Institutional Theory (implementation) models respectively. A great deal of modern processing and analysis techniques have been used to determine the key factors that affect the implementation and acceptance of e-government services (G2E) in the MoE. The research aims will be achieved using a multi-method approach which consists of qualitative (interviews) and quantitative (survey) methods to investigate practices and experiences of adopting and implementing e-government systems in Kuwait’s MoE. This thesis concludes with a summary of the contribution made by this work, its limitations and guidelines for future research. For the above discussion, the research presents a conceptual model from two models, Unified Theory of Acceptance and Use of Technology (UTAUT) model (adoption) and Institutional Theory (implementation). A great deal of modern processing and analysis techniques used to determine the key factors that affect the implementation and acceptance of e-government services (G2E) in the ministry of education. To achieve the research aims a multi-method was adopted, qualitative (interviews) and quantitative (survey) methods to investigate practices and experiences of adopting and implementing e-government systems in the ministry of education in Kuwait

Design and implementation of 2.6 GHz Phase shift using microstrip technology for mobile broadband application

This paper evolves transmission line phase shifting to optimize system cost. The design of a 1 x 2 microstrip (patch) array antenna which has an operating frequency of 2.6 GHz. Substrate FR4 dielectric with dielectric constant of 4.4 and thickness of 1.6 mm is utilized in array design. The study is performed in four steps: Firstly, through simulating radiation pattern on CST by altering two independent parameters; Spacing between patches and differential length of transmission line from source to each patch antenna. Secondly, a fabrication has been done on a sample deferential length to two ports that simulating two microstrip (patch) antennas array. Thirdly, testing of radiation fields has been performed to verify the correlation between actual records and the simulated designed antenna phase shifting. Fourth and finally, A comparison of results has been included between this paper results and previous works in sake of showing the introduced effort added value

Hydrothermal synthesis of (C5H14N2)[CoCl4]⸳0.5H2O: Crystal structure, spectroscopic characterization, thermal behavior, magnetic properties and biological evaluation

The organic-inorganic compound (C5H14N2)[CoCl4]⸳0.5H2O, I, was characterized by various physicochemical techniques. The X-ray diffraction analysis revealed that the compound crystallizes in the centrosymmetric space group C2/c of the monoclinic system. The atomic arrangement the Co(II) complex is built from isolated [CoCl4]2– anions, 1-methylpiperazine-1,4-diium [C5H14N2]2+ cations and free water molecules. The crystal structure study showed that the cohesion of I is assured through N–H···Cl and N–H···O hydrogen bonds giving birth to a 3-D architecture. Hirshfeld surface analysis revealed that Cl···H/H···Cl and H···H (58.5 and 36.4%, respectively) are the most significant interactions between species. Minor O···H/H···O interactions are also present. The compound was characterized by thermal analysis, TGA-DTA showed the removal of the co-crystallized water before 100 °C and a first mass loss at around 120 °C. Magnetic measurements are in good agreement with isolated, S = 3/2, tetrahedral [CoCl4]2− anions. The negative Weiss constant of -1.35 indicates single-ion anisotropy and very weak antiferromagnetic interactions. UV–visible spectroscopy reveals three weak absorption bands in the visible range due to the d-d electronic transitions typical of the Co(II) tetra-coordinated. A bioassay showed antibacterial activity against the gram negative Klebsiella pneumonia and gram positive Bacillus ceureus, Listeria monocytogenes, and Micrococcus lutues
