This paper presents an implementation of the Ant Colony Algorithm for the Vehicle Routing Problem (VRP). For the calculation of the best way between two adjacent points in the route, the classical algorithm of Dijkstra was used. Field activities and tests were carried out in different collective organisations, and collection and distribution route maps were created for each pilot-organisation. During the development of the system, some processes were revised in order to better adjust the routes, after considering the parameters related to cost, time and sales volume. The main difficulties in the development of this system were related to the adaptation of the standards proposed by urban routing systems to a rural context. Also, concerning the future trends of the model, many efforts have been made to improve the geographical interface and to test other VRP algorithms, like VRP with time windows and Dynamic VRP.

The importance of adopting the evolutionary maintenance is becoming increasingly long life of a software without it losing its quality and its functionalities, however performing evolutionary maintenance of legacy systems is not always an easy task, considering that these systems often have incomplete and inconsistent documentation or even that was lost over time. We want to understand what software process assets can help in the implementation of requirements development practices in evolutionary maintenance in adherence to CMMI-DEV model, how these assets can be used by requirements team and how this team evaluate this application. This paper aims to present an implementation approach of the RD (Requirements Development) process area of CMMI-DEV (Capability Maturity Model Integration for Development) in the Brazilian company, called Vibe Desenvolvimento, for evolutionary maintenance projects with data collection from reverse engineering, and perform the adherence analysis of the model implemented in relation to the process area studied, through the application of questionnaires to Requirements Analyst team of this company, and the analysis of the work products generated in each specific practice of RD process area. © ISCA, CATA 2017.

Cancer classification through gene expression data analysis has emerged as an active area of research recently. Gene expression is the process of transcribing a gene's DNA sequence into RNA. A gene's expression level indicates the approximate number of copies of that gene's RNA produced in a cell. This is thought to correlate with the amount of the corresponding protein made. The expression of a gene provides a measure of activity of a gene under certain biochemical conditions. For example, cancers are usually reflected in the change of the expression values of certain genes. Recent studies on molecular level classification of tissues have produced remarkable results, and indicated that gene expression assays could significantly aid in the development of efficient cancer diagnosis and classification platforms. However, cancer classification based on the DNA array data is still a difficult problem. The main challenge is the overwhelming number of genes relative to the number of training samples. This implies that we must deal with a huge number of irrelevant genes. An efficient algorithm is required to reduce the computational overhead. The other challenge is from the presence of noise inherent in the data set. It makes accurate classification of data more difficult when the sample size is small. This paper applies genetic algorithms (GA) for selecting a group of relevant genes from cancer microarray data. Then the decision tree based cancer classifier is built on top of these selected genes. The performance of this approach is evaluated by comparing with other gene selection methods (e.g., t-statistics, GS method, and information gain) using the publicly available gene expression data set such as Colon, Leukemia, Lymphoma, Lung and central nervous system (CNS). Experimental results indicate that the cascade of GA and decision tree has the highest accuracy rate among different methods.

with the development of digital technology online payments can be made for various purposes. At present, the Indonesian tax directorate general has implemented an E-billing system that can be used by the public to make tax payments online. E-billing is available in the form of web-based and mobile applications in order to facilitate the public in making payments. However, in reality, there are still many people who prefer to use traditional methods of paying taxes. Initial allegations, these problems relate to web design factors, design applications, and website quality from the E-billing system. This paper examines the factors that relate to people's satisfaction with the decision to use the E-billing system. © 2018 IEEE.

Improvement of pressure ulcers (PU) images analysis through computerized techniques is advantageous both to medical assistance institutions and to patients' life quality. The scientific challenge is to improve assistance to patients with PU by means of reliable image analysis procedures. Diagnosis of stage and predominant texture in a PU is essentially an image colour classification problem that can use existing knowledge. This study performs a classification of pressure ulcers images through an algorithm based on ID3 to construct a decision tree that has RGB statistics as input features and PU stage and texture as target features. A decision tree is constructed first by classification of 18 images of a training set. Then this tree is tested in a set of 45 PU images. Acceptable classification accuracy for training sets was not confirmed in test set.

The interaction of fast charged particles with graphene layers can generate electromagnetic modes. This wake effect has been recently proposed for short-wavelength, high-gradient particle acceleration and for obtaining brilliant radiation sources. In this study, the excitation of wakefields produced by a point-like charged particle moving parallel to a multilayer graphene array (which may be supported by an insulated substrate) is studied using the linearized hydrodynamic theory. General expressions for the excited longitudinal and transverse wakefields have been derived. The dependencies of the wakefields on the positions of the layers and the substrate, the velocity and the surface density have been extensively analyzed. This study provides a deeper understanding of the physical phenomena underlying plasmonic excitations in graphene layers, paving the way for potential applications of these structures in particle acceleration, nanotechnology and materials science. © 2025, CC BY-NC-ND.

In recent years, a lot of research concerns with the wireless sensor networks (WSN). With the increasing usages of WSN applications such as health care and disaster reporting, security requirements, wireless communication has become more critical. Researchers of intrusion detection system on WSN have suggested that systems' detecting mechanisms would likely affect their detections effective and lifetime of whole networks. Ontology can collect and organize the attributes of attacks However, those methods have empirically documented the link between ontology concept and lightweight Intrusion Detection System (IDS) is scant. Therefore, the aim of this paper attempts to explore how intrusion detection system about ontology and light-weight IDS are related. The manager constructs relationship of sensor nodes on ontology to detect Sybil attack. Combine light-weight IDS the ranger method to reduce energy consumption and the isolation tables avoid detecting anomaly repeatedly. We proposed a lightweight ontology-based IDS, which improves existence shortcomings of IDS on WSN effectively. © 2011 IEEE.

A data model supporting the unification of the management of temporal XML document databases and version control, i.e., a Temporal Version Data Model (TVDM), is proposed. TVDM is temporally change-centric and represents the change between two consecutive versions by means of temporal delta (tDelta). A tDelta employs a temporal XML expression (tXex) which is an extension of ordinary XML elements by incorporation into them temporal as well as ordinary variables. In addition to valid time, TVDM introduces version time and associates it with each version. All versions including the base or the current one can be uniformly represented by tDeltas. A technique to implement TVDM is also presented. © Springer-Verlag Berlin Heidelberg 2004.
