Genetic Programming Testing Model

Genetic Programming Testing Model

Depending on the nature of the model used, software testing is called functional testing (also called specification-based testing) or structural testing (also called implementation-based testing). Models used in functional testing are based on software functional requirements while in structural testing are based on the software’s internal structure. Nowadays, the most part of software testing is done using functional testing techniques, since they are less costly. However, as research works have been focused on structural testing, software industries do not have many formal ways to perform and assess the test of their products and end up using just heuristics to carry out their software testing [4]. A functional testing technique that has been commonly used in the software industry is Model Based Testing (MBT)[5]. The modeling technique most used to create such models is the Finite State Machines (FSMs). Besides software modeling, the FSMs are used as a basis to define functional testing criteria to be applied in test case selection and adequacy analysis. The FSMs are considered an excellent tool for software modeling, user/developer communication and testing, since their application is simple and intuitive. Although traditional

ERP ASSIMILATION: AN END-USER APPROACH

ERP ASSIMILATION: AN END-USER APPROACH

Abstract: One premise of this paper is that ERP implementation is an “organization wide revolution” because a large number of changes happen. Unfortunately, after 20 years of experience, many implementations of ERP systems take longer and cost more than projected or even fail. As many authors stated, one major cause appears to be that organizational issues are neglected or underestimated. In this type of IT project the organizations confront with many problems because they put inadequate stress on the management of change brought about by the technology. We consider that the success of the implementation depends highly on the company’s openness to change. Change is not always welcomed by end-users, so the first step is to ensure that the executive management supports the team’s vision, the vendor selection and the implementation project from beginning to completion. When an ERP software provider is selected, it should display the qualities and be prepared to act as a “change agent”, one who can explain short-term and long-term benefits of the proposed changes, while being sensitive to each end-user’s level of change acceptance. Our study was focused on the end-users behaviour and perception.

STRATEGY FOR EVALUATION AND SELECTION OF SYSTEMS FOR ELECTRONIC LEARNING

STRATEGY FOR EVALUATION AND SELECTION OF SYSTEMS FOR ELECTRONIC LEARNING

The sixth generation of e-learning systems has reach the top in last few years. A significant increase of systems for electronic learning requires a precise evaluation of the functionality that those systems provide. With qualitative evaluaition they can be compared. In most cases, when we implementing a system for e-learning, it is necessary to hire an e-learning system experts who will help us to prevent unnecessary waste of resources, time and money. Another key point for successful implementation is to make a project for implementation of e-learning systems because it is the only way to reduce risks and increase chances. A huge number of systems for e-learning offers a multiple choices. For the quality evaluation is it necessary to chose a system that offers us exactly what we want with the least investment. E-learning in the teaching process imposes the question of quality of electronic education. Compared with traditional instruction, e-learning has many peculiarities. First e-learning requires extensive technical knowledge, information and computer literacy, adequate equipment, multimedia presentation, also physical and virtual contact between teachers and students. E-learning systems generally use a web interface that realizes the communication between users and the systems. Also there is a question of adaptability of learning material which includes the user interface and the ability of transition to a new system if we choose to replace the old. Besides the flexibility in choosing LMS it is necessary to pay attention to system durability because LMS requires new resources and computer upgrades. Design and implementation are the final process in implementing system for electronic learning.

Criterion for selection the optimal physical and chemical properties of cobalt aluminate powder used in investment casting process

Criterion for selection the optimal physical and chemical properties of cobalt aluminate powder used in investment casting process

important factor, which influences the grain size and the quality of the casting is the amount of modifier introduced into the mould. The amount of cobalt aluminate in the primary slurry is highly variable, (ranging from 1 to 10% or higher) and depends on the specification requirements, the alloy being casted, the section thickness, and other factors [9-11]. On the grounds of the obtained results it was found that the optimal concentration of cobalt aluminate powder in ceramic mould to produce casting elements made from Inconel 713C superalloy is about 5-6%mass, however in case of S6K - 2%mass. The higher concentration of modifier does not change the grain size significantly and does not improve mechanical properties of castings. So the next step in the study is to define what chemical and physical properties should cobalt aluminate characterize in order to archive the best nucleating effect.

Comparative study of risk administration in centralized and distributed software development atmosphere

Comparative study of risk administration in centralized and distributed software development atmosphere

In multi-organizational development, participating teams work for different organizations. Multi- organizational development can be either: Contractual, with one central authority (either one of the developer organizations or, less repeatedly, a customer) and other teams functioning on particular components with watchfully specified predefined inter-faces and behavior, or accommodating, with teams functioning on sub- systems or low joined components with iteratively specified interfaces and performance, often without a clear, generally accepted central authority for resolving differences and conflicts. Both distributed development (Beranek et al., 2005) and Centralized software development (Deek and McHugh, 2003) introduce a number of new risk administration concerns and change or intensify others.

Implementation of Phonetic Context Variable Length Unit Selection Module for Malay Text to Speech

Implementation of Phonetic Context Variable Length Unit Selection Module for Malay Text to Speech

Abstract: Problem statement: The main problem with current Malay Text-To-Speech (MTTS) synthesis system is the poor quality of the generated speech sound due to the inability of traditional TTS system to provide multiple choices of unit for generating more accurate synthesized speech. Approach: This study proposes a phonetic context variable length unit selection MTTS system that is capable of providing more natural and accurate unit selection for synthesized speech. It implemented a phonetic context algorithm for unit selection for MTTS. The unit selection method (without phonetic context) may encounter the problem of selecting the speech unit from different sources and affect the quality of concatenation. This study proposes the design of speech corpus and unit selection method according to phonetic context so that it can select a string of continuous phoneme from same source instead of individual phoneme from different sources. This can further reduce the concatenation point and increase the quality of concatenation. The speech corpus was transcribed according to phonetic context to preserve the phonetic information. This method utilizes word base concatenation method. Firstly it will search through the speech corpus for the target word, if the target is found; it will be used for concatenation. If the word does not exist, then it will construct the words from phoneme sequence. Results: This system had been tested with 40 participants in Mean Opinion Score (MOS) listening test with the average rates for naturalness, pronunciation and intelligibility are 3.9, 4.1 and 3.9. Conclusion/Recommendation: Through this study, a very first version of Corpus-based MTTS has been designed; it has improved the naturalness, pronunciation and intelligibility of synthetic speech. But it still has some lacking that need to be perfected such as the prosody module to support the phrasing analysis and intonation of input text to match with the waveform modifier.

Reinforcing Herzog´s point of view, related to the importance to analyze functional adjustment, Correa (2008, p.96) reflects on the fact that in private ERPs, due to years of evolution, there is a great number of better practice processes available. In some Open Source solutions there are only “basic processes available, such as purchase orders, sales, stock, bills receivable, and accounting, among others”. The author also highlights specific cases of companies with highly customized processes, and few of them benefited by the existence of “better practices” in the system, which does not justify the cost of adopting private solutions.

A Scheme to Optimize Flow Routing and Polling Switch Selection of Software Defined Networks.

A Scheme to Optimize Flow Routing and Polling Switch Selection of Software Defined Networks.

To reduce the communication cost for collecting all the flow informations in SDN, one switch-based method called FlowCover [5] is proposed. FlowCover requests selected switches (referred as polling switch) to send the statistics of all flows on it. It should be guarantee that at least one polling switch is traversed by each flow. In this way, some request and reply packets of flow statistics are aggregated. However, this method may bring some duplicate pollings on the controller because the controller may poll same flows on different polling switches. The duplicate pollings bring extra resource consumption of switches and controller, such as more TCAM memory entries, and may result in the overuse of limited resources. For example, paper [6] shows the monitor rules of measurement require memory space, but the switch memory is limited as discussed in [7–10]. The TCAM memory is expensive (US$ 350 for a 1 M-bit chip) and power-hungry (about 15 Watt / 1 Mbit) as shown in [11]. Therefore, although switch- based method saves lots of communication cost, it may cause more resource stress on switches and controller than the flow-based method.

Crop data retrieval using earth observation data to support agricultural water management

Crop data retrieval using earth observation data to support agricultural water management

Accurate crop data are essential for reliable irrigation water requirements (IWR) calculations, which can be acquired during the crop growth season for a given region using earth observation (EO) satellite time series. In addition, a relationship between crop coefficients and the NDVI can be established to allow for crop evapotranspiration estimation. The main objective of the present work was to develop a methodology, and its implementation in an application software, to extract crop parameters from EO image time series for a set of parcels of different types of crops, to be used as input data for a soil water balance model to compute IWR. The methodology was tested at two distinct test sites, the Vila Franca de Xira (site I) and Vila Velha de Ródão (site II) municipalities, Portugal. Landsat-7 and -8 images acquired from April to October 2013 were used for site I, while SPOT-5 Take-5 images from April to September 2015 were considered for site II. EO data were used to estimate the basal crop coefficients, planting dates, and crops growth stage lengths. Based on crop, soil and meteorological data, the IWR for the main crops of both test regions were estimated using the IrrigRotation model. The crop coefficient curves obtained from the EO data proved to be reliable for IWR estimation.

The current CRM solutions market is undergoing deep changes. Since 1999 a number of merges and takeovers have favoured significant changes in terms of CRM and ERP scene agents, to the extent that currently the main players of these traditional market segments are essentially the same ones. The initial business model based on the sale of software licences has been combined with the irruption of the ASP model (internet based), which allows organizations with lower incomes to adopt this kind of technology with a lower risk and technological infrastructure, apart from reducing expenses. According to Gartner, SAP is the market leader closely followed by Siebel, Peoplesoft, Oracle and Salesforce.com. This latter company offers their services only following the ASP business model.

Genital evolution: why are females still understudied?

Genital evolution: why are females still understudied?

Abstract: The diversity, variability, and apparent rapid evolution of animal genitalia are a vivid focus of research in evolutionary biology, and studies exploring genitalia have dramatically increased over the past decade. These studies, however, exhibit a strong male bias, which has worsened since 2000, despite the fact that this bias has been explicitly pointed out in the past. Early critics argued that previous investigators too often considered only males and their genitalia, while overlooking female genitalia or physiology. Our analysis of the literature shows that overall this male bias has worsened with time. The degree of bias is not consistent between subdisciplines: studies of the lock-and-key hypothesis have been the most male focused, while studies of cryptic female choice usually consider both sexes. The degree of bias also differed across taxonomic groups, but did not associate with the ease of study of male and female genital characteristics. We argue that the persisting male bias in this field cannot solely be explained by anatomical sex differences influencing accessibility. Rather the bias reflects enduring assumptions about the dominant role of males in sex, and invariant female genitalia. New research highlights how rapidly female genital traits can evolve, and how complex coevolutionary dynamics between males and females can shape genital structures. We argue that understanding genital evolution is hampered by an outdated single-sex bias.

Analysable Software Language Translations

Analysable Software Language Translations

In the Decision phase, we also elicit the requirements of the to be built Software Language in order to answer questions such as: Do we really need a new Software Language? This does not differ so much from deciding if it is reasonable to build a new product line, since we have to take into account the reuse factor of existing products that can now (with a new software language) be automatically gener- ated and verified, versus the whole cost of building a completely new software language. The Domain Analysis phase involves a thorough research in the ter- minology used in the domain, by looking into existing documentation such as Problem and Solution Descriptions. The rules of the domain under study may be either implicitly or explicitly defined, therefore we usually also need to perform informal interviews with the experts of the domain, and a survey of the existing tools such as: general purpose editors, simulators, compilers/interpreters, and general purpose execution engines (e.g., Java Virtual Machine). This particular kind of analysis, also called Co-Domain Analysis, involves the analysis of the variability at the level of the implementation (target) platforms. Here, we study the target platform variability, the same way we do for Software Product Lines. This variability model can be expressed by means of Feature Models using a Fea- ture Model language [CHE04].

The Impacts of well Planned Recruitment and Selection Process on Corporate Performance in Nigerian Banking Industry (A Case Study of First Bank Plc 2004-2011)

The process of searching for a new employee is customarily initiated by a manager who decides that he needs to add to his staff or to replace someone who is leaving the organization. Commonly he makes a written request to the personnel department stating that he wishes to hire someone to fill a vacancy. The position to be filled is defined in terms of its job description and its job specification. The hiring activity should be integrated with the human resource plan of the company. These plans should forecast department that are expected to grow and those that may decline. There should be a skill inventory so that present employees can be matched with job openings to provide for transfers and promotions.

Risk Management Adoption Framework for Software Projects: A Case Study for Kenyan Software Project Managers and Developers

Risk Management Adoption Framework for Software Projects: A Case Study for Kenyan Software Project Managers and Developers

Kenyan practitioners poorly understand the area of risk management and have very bad attitude towards it. “This shows that, it is not lack of suitable models to help us structure our thinking in this domain; but the real problem is insufficient awareness of current best practices and published standards in software development, management and quality” [26]. Wiegers’s sampling report showed that only 10% of the sampled audience members had access to the widely known IEEE Software Engineering Standards. The rest were not aware of their existence [26]. Our study revealed that 81% of participants were not aware of proper risk management practices. This gives us reason to conclude and rate awareness as the main cause for lack of proper risk management practices in Kenyan software projects as illustrated in the model, Figure 5.

Improvement of performance indicators after Scrum re-implementation in software development teams

Improvement of performance indicators after Scrum re-implementation in software development teams

Smart homes, tech gadgets, and virtual assistants are now part of everyday life and everyone is being affected by them. Related to maps, the trend is definitely knowing what's going on around you in real time and being able to visualize your own location on the map, wherever you are. The main trends developing in the market will be Location Based Services and Personal Digital Assistants, giving the user the ability to access information from online sources. In 2050, there will be an additional 2.5 billion new people in the world - most of which will be living in urban areas. Driven by increasing economic globalization, urbanization levels are anticipated to reach 66%. Beyond the positive environmental impacts that technology can drive - such as LED streetlamps, energy-efficient buildings, and the Internet of Things (IoT) - based products - it can also have significant social benefits in an increasingly urbanized world (Technavio, 2017). Outdoor advertising influences consumer behaviour more than the advertising at home, lately. The research found that people who have seen an out-of-home advert are 17% more likely to interact with the brand. The opportunity here lies in collaborations with DOOH screens and kiosks providers.
