To date, cancer of uterine cervix is still a leading cause of cancer-related deaths in women worldwide. The current methods (i.e., Pap smear and liquid-based cytology (LBC)) to screen for cervical cancer are time-consuming and dependent on the skill of the cytopathologist and thus are rather subjective. Therefore, this paper presents an intelligent computer vision system to assist pathologists in overcoming these problems and, consequently, produce more accurate results. The developed system consists of two stages. In the first stage, the automatic features extraction (AFE) algorithm is performed. In the second stage, a neuro-fuzzy model called multiple adaptive neuro-fuzzy inference system (MANFIS) is proposed for recognition process. The MANFIS contains a set of ANFIS models which are arranged in parallel combination to produce a model with multi-input-multioutput structure. The system is capable of classifying cervical cell image into three groups, namely, normal, low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intraepithelial lesion (HSIL). The experimental results prove the capability of the AFE algorithm to be as effective as the manual extraction by human experts, while the proposed MANFIS produces a good classification performance with 94.2% accuracy.

Swarm intelligence is a branch of artificial intelligence that focuses on the actions of agents in self-organized systems. Researchers have proposed a bee colony optimization (BCO) algorithm as part of swarm intelligence. BCO is a meta-heuristic algorithm based on the foraging behavior of bees. This study presents a hybrid BCO algorithm for examination timetabling problems. Bees in the BCO algorithm perform two main actions: forward pass and backward pass. Each bee explores the search space in forward pass and then shares information with other bees in the hive in backward pass. This study found that a bee decides to be either a recruiter that searches for a food source or a follower that selects a recruiter bee to follow on the basis of roulette wheel selection. In forward pass, BCO is supported along with other local searches, including the Late Acceptance Hill Climbing and Simulated Annealing algorithms. We introduce three selection strategies (tournament, rank and disruptive selection strategies) for the follower bees to select a recruiter to maintain population diversity in backward pass. The disruptive selection strategy outperforms tournament and rank selections. We also introduce a self-adaptive mechanism to select a neighborhood structure to enhance the neighborhood search. The proposed algorithm is evaluated against the latest methodologies in the literature with respect to two standard examination timetabling problems, namely, uncapacitated and competition datasets. We demonstrate that the proposed algorithm produces one new best result on uncapacitated datasets and comparable results on competition datasets. © 2014 Elsevier Ltd.

This paper presents an adaptive neuro/fuzzy system which can be trained to detect the current human emotions from a set of measured responses. Six models are built using different types of input/output membership functions and trained by different kinds of input arrays. The models are compared based on their ability to train with lowest error values. Many factors impact the error values such as input/output membership functions, the training data arrays, and the number of epochs required to train the model. ANFIS editor in MATLAB is used to build the models. © 2013, Malkawi and Murad; licensee Springer.

Web caching has been used extensively to enhance web delivery to clients by minimizing the latency perceived by clients, reducing network bandwidth usage, reducing power consumption and improving the network quality of service. Caching performance can be improved by implementing an efficient replacement policy to be used for proper cache replacement. In mobile networks, the movement of users presents significant technical challenges to provide efficient access to the Internet, because the mobile users' locations and the network attachment point will vary in time. In this survey, various conventional replacement policies for the mobile environment proposed in literature is listed and classified based on the methodology used in eviction. © 2015 IEEE.

The goal of this paper is to examine the empirical dynamic relationship among the electrical consumption (ELC) and economic growth (proxies by gross domestic product [GDP] per capita), export, and financial development (domestic credit to the private sector as a percentage of GDP) in Jordan over the 1976-2011 period. Annual time series data and the autoregressive distributed lag model are used. The augmented Dickey–Fuller, F-bound testing, Granger causality, GIRF, and cumulative sum of recursive residuals, cumulative sum of squares tests were applied to test the stationary, cointegration, causality and stability, respectively, among the variables. There is evidence of a long-term equilibrium relationship between electricity consumption and the economic growth, and a unidirectional relationship runs from real GDP to ELC. This is indicating that per capita increase in economic growth may cause a perpetual rise in the ELC in Jordan. © 2015, Econjournals. All rights reserved.

Artificial Bee Colony Algorithm (ABC) is nature-inspired metaheuristic, which imitates the foraging behavior of bees. ABC as a stochastic technique is easy to implement, has fewer control parameters, and could easily be modify and hybridized with other metaheuristic algorithms. Due to its successful implementation, several researchers in the optimization and artificial intelligence domains have adopted it to be the main focus of their research work. Since 2005, several related works have appeared to enhance the performance of the standard ABC in the literature, to meet up with challenges of recent research problems being encountered. Interestingly, ABC has been tailored successfully, to solve a wide variety of discrete and continuous optimization problems. Some other works have modified and hybridized ABC to other algorithms, to further enhance the structure of its framework. In this review paper, we provide a thorough and extensive overview of most research work focusing on the application of ABC, with the expectation that it would serve as a reference material to both old and new, incoming researchers to the field, to support their understanding of current trends and assist their future research prospects and directions. The advantages, applications and drawbacks of the newly developed ABC hybrids are highlighted, critically analyzed and discussed accordingly. © 2005 - 2013 JATIT & LLS.

This study investigates the effect of financing structure in achieving profits and distributing dividends, and the interactive effect between them, in order to help companies improving their profits and dividends policy. The study was carried on a population consists of the Jordanian public industrial companies. A random sample of (47) companies was selected, that having all required information for the period from 2008 to 2014, simple and multiple regression was used to test the hypotheses of the study. The main results of the study were: there is a negative effect to the liabilities (debt funds) on the income, and positive effect to the capital paid and returned earnings on the income, and the effect of the dividends on the income is more than the effect of the income on the dividends of Jordanian industrial companies, The researcher can reach to different recommendations the most prominent was Securities official bodies and authority in Jordan must increase their interest in the financial market efficiency by enabling the Jordanian industrial companies issuing new financial instruments such as preferred shares in facilitating terms, and helping companies to obtain financing sources, thus enabling these companies to take advantages of investment opportunities and reach to the idle financing structure, that maximizing the wealth of the owners and the value of the company. © Maswadeh Sana’a N, 2016.

This study investigates the effect of accounting conservatism as independent variable and size of the company as a control variable on financial indicators related to the performance of Jordanian insurance Companies, represented in return on asset, earnings per share (EPS), and market value of the share, for the period (2007-2014). The researcher has collected the necessary data from annual reports issued by insurances companies listed in Jordan Securities Exchange Commission (SEC). The study sample consisted of (12) Jordanian Insurance companies. For determining whether the Jordanian insurance companies has practice accounting conservatism policies, the study used accruals based approach; in order to test the hypotheses of the study it has been used multiple regression analysis. The most important results are: The Jordanian insurance companies have practice accounting conservatism policies, and there are significant and positive effect of accounting conservatism policies on financial indicators related to the performance of the Jordanian insurance companies represented in:, return on asset and earnings per share (EPS), and market value of share, for the period (2007 to 2014). According to of the above results the researcher concluded many recommendations the most prominent is the increased oversight of the securities Exchange commission, the organizers of the accounting profession and the official supervisors of organizing the companies’ work in Jordan, adopt the appropriate procedures in order to encourage companies to commitment to an acceptable accounting conservatism level. © Sana’a NM, 2016.

The remarkable growth in electronic commerce constitutes another new challenge for the accounting profession in its effort to meet the rapid and continuing revolution of information changes. Therefore, the objective of this study is to investigate the important obstacles facing corporations working in the business of E-commerce. This study also aims to investigate the production of accounting information as related to level three (recognition and measurements) of the conceptual framework underlying financial accounting. Therefore, to achieve the primary objectives of this study the researcher has developed a questionnaire that has been distributed to Jordanian external auditors. A total of 77 questionnaires were distributed; however, only 71 questionnaires were suitable for the analysis. A sample t- test was used to test the hypotheses of the study. The main results of the study revealed high arithmetic mean related to the obstacles of the accounting concepts (principles, assumptions, and constraints) at level three of the conceptual framework that underlies financial accounting. This requires attention in the preparation of the financial reports of a corporation operating in E-commerce Business. Moreover, the research concludes that the obstacles are connected, interdependent and interrelated with each other. Therefore, the accounting principle obstacles have implications over the application of accounting assumptions and constraints. Consequently, the researcher recommends the need to make changes in the concepts of recognition and measurements in the conceptual framework that underlies financial accounting. This is to ensure the qualitative characteristics of accounting information for E-commerce business corporations. © Sana’a NM, 2016.

Office-Space-Allocation problem is a distribution of a set of limited spaces to a set of resources subject to two types of constraints: hard and soft. Hard constraints must be fulfilled while the soft constraints to be satisfied as much as possible. The quality of the solution is determined based on satisfaction of the soft constraints and the best usage of spaces. The harmony search algorithm (HSA) is a population-based metaheuristic inspired by a musical improvisation process. At each iteration, three operators are used to generate the new harmony: memory consideration, random consideration, and pitch adjustment. In this paper, we modify the memory consideration operator to select from the best solution in the population during the search. HSA is evaluated by using three datasets from Nottingham, and Wolverhampton universities. Experimentally, the HSA obtained new results for two datasets, and a comparable result for the third dataset. © 2012 Springer-Verlag.
