The Constructive and Technological Preparation of Production
Authors: Dima I. C. , Grabara Janusz
Published: December 2012

Making any industrial product requires a good constructive and technological preparation of the production process by means of which that product is obtained. To start with, it is necessary to codify and classify the products by using various methods such as ABC, OPTIZ, CETIM PNG, etc., and the constructive preparation of production implies the use of an appropriate methodology mainly based on the product functions. The products can be the result of the production process achieved by integrating the production, which is always based on a multi-criteria decision. Regardless of whether production is integrated or not, it is necessary to schedule the production by shaping based on the deterministic models with the discreet and continuous structure or on the probabilistic models with the discreet and continuous structure. The technological preparation of scheduled production manufacturing is based on the economical-mathematical models and uses the matrix of multi-criteria manufacturing consequences. In order to select the best manufacturing system, the simulation of the production processes may be applied by using a simulation model in order to schedule the production by using appropriate production technologies. The quality of any manufactured product determines a certain level of related costs, and a product of inappropriate quality determines costs of non-quality both at the manufacturer and user of that product.
The Management of Basic Production Functions
Authors: Dima I. C. , Modrák Vladimir
Published: December 2012

The production achieved in any industrial company is generically called basic production that needs an appropriate management that is different for every type of mass, serial, or individual production. Every type of production is based on a set of mathematical restrictions that quantitatively and qualitatively quantify that type of production. The fundamentals of the management of any basic production refers to: the production cycle that has a certain structure, and the total duration, the size of which considers both the way that product is made and the graph of moving the benchmarks from one operation to another; the manufacturing batch and, respectively, the optimal manufacturing batch, meaning the time elapsed between the release into production of two consecutive batches. A special case is the production achieved on a single object and multiple object flow manufacturing lines variably and constantly, continuously and discontinuously, etc. Every flow manufacturing line has a certain cadence, a certain tact, generates certain costs, and has certain characteristics. In the case of control production, it can be organised by taking into account the product position or the nature of the manufacturing process. Every type of production generates costs that are different in terms of the structure and calculation, and the use of the electronic calculation technique is imperatively necessary.
Auxiliary Production Management
Authors: Dima I. C.
Published: December 2012

Besides the basic production achieved in any company, there is also an auxiliary production influencing the smooth performance of the basic production process. Thus, an efficient basic production is inconceivable without equipping the machines and plants with SDVs (Verifying Devices Tools), without needing the reorganisation and modernisation of machines and plants, the timely maintenance and repair of working machines and plants, etc. The repair activity is based on the repair cycle structure—technical overhauls, current repairs, overall repairs—the selected method for performing the repairs—as needed, by firm planning, after controlling the state of the machines, preventively-planned, etc.—how to perform the repairs—centralised, decentralised, mixed—etc. The modernisation and reorganisation of the machines applies the method of single indicators, the method of the indicators systems, the method of comparing costs in time and space, etc. The production of SDVs is based on their structure and classification and implies both the activity to design them based on some appropriate methods and the way to locate and structure the departments or divisions that produce SDVs. The energetic department—thermal power, electrical power, compressed air—plays a very important role in any industrial company and refers to the manufacture and use of power.
Operative Management of Industrial Production
Authors: Dima I. C. , Paunovic
Published: December 2012

Conceptually, the operative management of industrial production is in fact the operative management of all an industrial company’s functions, meaning the operative management of development research, of commercial activity, of financial-accounting activity, of human resources, of logistics. The operative management is in fact a component of the industrial company’s management, and under the structural aspect, it includes programming, releasing, monitoring, controlling, and re-updating the production schedules. In the operative management, the dispatcher emphasises the management of the system led by the leading system, taking into account a certain flow of information. The use of the data processing computerised system in the operative management leads to establishing the system of an industrial company’s aggregated indicators by fields of activity, meaning for production, commercial activity, financial-accounting activity, human resources, etc. Making the operative management more efficient also implies the use of the balanced dashboard in its entire complexity, meaning the presentation of information regarding the clients, presenting the information on the development of the industrial company, etc.
Elements of Logistics Used in Industrial Operational Management
Authors: Dima I. C. , Grabara I.
Published: December 2012

Under the conditions of the current economic-social development within the industrial company’s management, there occurs a new function, that of logistics, which has a decisive influence on the company’s other functions. Thus, the industrial company’s logistics is systematically approached, emphasising its elements, namely: production logistics, commercial logistics, operational logistics, sales support logistics, pilotage logistics. In the industrial company’s organisational structure, logistics has an independent position, and the implementation of any logistical study within the company incurs costs related to the supply transportation, related to the distribution, related to the operation of warehouses, etc. These costs can be deemed as being total costs that depend on the total quantity that is subject to the logistical process. Any activity of logistics within the company can be analysed by means of a questionnaire called Logitest. The absence of the activity of logistics within the company or an inappropriate activity of logistics may lead to the occurrence of a logistic drama—the Logidram that emphasises the client-supplier conflict, the conflicts inside the company, the conflicts with the logistic operators, etc.
Scheduling the Production Obtained by Production Processes where Several Operations Are Performed and Repeated at Time Intervals Previously Set Forth for Various Products
Authors: Dima I. C.
Published: December 2012

Programming the production obtained by processing the raw materials in several operations that are repeated at certain time intervals previously set forth for various products aims the serial production organised by manufacturing batches. The size of the manufacturing series implies determining the optimal level of the manufacturing series that takes into account the correlation of the number of products that will be manufactured with the unitary expenses, which are in turn based on total expenses established according to the expenses incurred by the immobilisations of means and those related to the time to prepare-complete the manufacturing batch. The optimal size of the series influences the level of the manufacturing batch next to the size of the preparation-completion time, operative time, and manufacturing conditions. Based on the two previously established sizes, the duration of the manufacturing cycle is calculated, separately emphasising the duration of processing and of interruptions. Once the manufacturing cycle duration is established, the possible calendar moves forward and the size of the half-finished stocks necessary for the smooth operation of the flow manufacturing line is established. Balancing the scheduled production is to be done on that manufacturing line and takes into account its correlation with the production capacity for every workplace and each machine-operation during the period of repeatability of manufacturing batches and of the transport batches.
Managerial Systems, Methods, and Techniques Used in Scheduling Industrial Production
Authors: Dima I. C. , Man Mariana
Published: December 2012

The management of the industrial production implies the use of some management systems and methods that take into account the nature of production, production type, production volume, the way of organising its performance, etc. Normally, the following can be used: cost objective management system; managerial cost management system; target cost management system; expert systems used in industrial production management. Within these systems and methods of management, the main issue is to compare the estimated costs with the target costs. The process of implementing the management system based on the costs is complex and implies: establishing the objectives, breaking down the objectives set by responsibilities, regularly analysing the results obtained, changing the objectives regarding the level of costs should it be needed, etc. The costs corresponding to the last batch, margins of production added or subtracted from the previous volume of costs are the marginal costs that differ from the average costs which concern the entire production of the industrial company. The size of the marginal cost may be established as a total differential cost or as a unitary differential cost, both being in mutual inter-conditioning relation. The expert system in the operational management of production can be used with good results, which is based on comparing some specific facts to those in the databases. Any expert system takes into account the existence of several modules, such as the knowledge base, rule base, knowledge purchase module, inference engine, inference mechanism, etc.
Operational Production Structures Used in the Multi-Serving System
Authors: Dima I. C. , Novac-Marcincin Jozef
Published: December 2012

In terms of organisation, the production achieved by polyservice of machines and equipment implies the existence of some independent organisational links. The organisation of the polyservice activity by departments and workshops inside of which great importance should be given to the system of grouping the machines and equipment, studying the optimal conditions to locate them. Organising the production by single or multiple object, continuous or discontinuous flow, manufacturing lines takes into account: the parameters of the flow line, parameters concerning the labour force, the parameters of the machine-tools, technological parameters, etc. Another form of organising the production obtained through polyservice is the production departments in the composition of which there are numerically and automatically controlled machine tools. Organising the production obtained through polyservice may also be done in production departments, in the composition of which there are the transfer machine-tools, processing centres, and manufacturing cells. Organising the flexible manufacturing systems takes into account: the number of benchmarks that will be processed, reduction of the duration to design and make new products, typification and modulation of SDVs, equipping the machines and equipment with standardised SDVs, etc. The most efficient organisational form is the production departments in the composition of which there are the flexible manufacturing cells provided with industrial robots.
Using the Multi-Serving System in Textile Industry
Authors: Dima I. C.
Published: December 2012

Using polyservicing in the textile industry takes into account the distinctive particularities of this branch compared to the automotive industry, in terms of materials and processed materials, production equipment, manufacturing process, etc. Performers’ random interventions are specific to polyservicing in the textile industry during the unlimited duration of the manufacturing cycle. In case of servicing several knitting machines, the structure of the machine and servicing time is taken into account, calculating the constant value and use coefficient of each machine serviced. Polyservicing the knitting machines should also take into account the maximum number of jobs corresponding to the performer’s maximum load, maximum number of machines serviced and their optimal number established according to the production costs incurred, level of soliciting the performer, and its increase, etc. A special situation in the textile industry is the case of polyservicing several machines at certain random time intervals. In this case, mathematically modelling the polyservice is based on the theory of waiting strings or on Markov chain and takes into account the inputs or arrivals in the system, the performer’s service or effective action, the service factor in the system, the waiting discipline in the system, etc. Studying the polyservicing conditions in the textile industry implies calculating some indicators of the waiting times, the machines serviced in the system, the performer working in the system, etc.
Control of Industrial Production Management
Authors: Dima I. C. , Eric Dejan
Published: December 2012

The control of industrial companies is actually a managerial control aimed to regularise the company’s activity, so that the level of its achievements correspond to the preset objectives and standards. By the control activity, the forecast, organisation, coordination, drive, and motivation are enabled to contribute to achieving the objectives of the industrial companies. The control system is related to strategic, tactical, and operational planning, meaning that every form of planning must be controlled. The control is done after performing the control process that implies determining the controlled fields, determining the standards, determining the performance size, comparing the performance to the standards, etc. The managerial decision to control may lead to several types of control, namely: by synchronising the cycles (pre-operative, current, post-operative), multiplicative, simultaneous, cybernetic, non-cybernetic, market, bureaucratic, group, etc. Regardless of how it is, control meets several functions: means of information, means of motivation, means of sanctioning, etc. The current ways for developing the managerial control aim to adapt the system to the evolution of the motivation system based on negative sanctions and positive sanctions. Specifically, the management by objectives and participative management by objectives had good results.

Published: December 2012

Corporate education is centred on introducing learning techniques to stimulate employees to think about what their organisation does, where it is heading, potential new opportunities for the organisation, and new and better ways of doing things. While the role of corporate training is to develop the operational competency of individuals, the purpose of corporate education is to promote the development of capability of both an individual and their organisation. Organizations operating in knowledge economies require a workforce that has knowledge about other business functions along with their specilized area. In the last decade corporate training turned into corporate education in Turkey. As an important business function, accounting is one of the most preferential training subject in Turkey. The purpose of the chapter is to identify differences between corporate education and corporate training. Additionally, the study explains growing importance of corporate education in accounting area for Turkish business life.
NGOs and Corporate Education
Authors: Sinha Ravi , Gaurav Mrinal
Published: December 2012

Knowledge development at the regional level is basic to the strengthening of knowledge economy. Though there are many examples of universities taking up community service learning (CSL), they are alarmingly preoccupied with student outcomes and institutional interests. They focus more on achieving academic aims and bolstering the interests and power base of the academy, rather than fulfilling the goals of knowledge economy. Chandra and Mahato (2011) opine that in recent years, Non Governmental Organizations (NGOs) have emerged as powerful sources for social change within developing countries. Since the vast majority of them exist outside of the government, their programs emanate more from the expressed needs of the people rather than from governments. The participation of local level bodies including NGOs in establishing partnerships with universities is crucial for knowledge economy development. This can help in developing research networks that serve as a basis for regional level business or entrepreneurship that can be in tune with global economy. In the present chapter, the authors take a case study from Jharkhand (one of the states in India) to discuss how NGOs can help in corporate education and the role of Universities to promote their activities.

Published: December 2012

In recent times, the higher education in India has made tremendous progress in terms of increasing the access and thereby making it reachable to larger population of the country. However, post-globalization, internationalization, and marketization the higher education has been increasingly perceived as a professional service. This necessitates reworking on various facets pertaining to the higher education domain such as academics, administration, governance, teaching-learning process, consultancy, and grants earning initiatives. Therefore without any qualm, the paradigm shift is on the agenda of our universities and the process of reflection, reworking, self-critique, action, participation, improvement, collaboration, inclusion are now the buzzword inviting the renewed attention of our academicians and administrators. Easier said than done, in this chapter, the authors discuss some of the initiatives at state university and a newly commenced central university, wherein they could become the part of the reforms in reworking the model of the higher education. The same is put forth in front of the peers and stakeholders as a sort of action research towards inculcating professionalism in our universities.
Preparing Bio-Entrepreneurs

Published: December 2012

The Indian life science industry broadly comprises manufacturers and service providers. The manpower for both these sectors has to come through the institutes of higher education, mainly the universities. In order to create newer jobs, encouraging start-up enterprises is very much essential. The present day university life science education prepares graduates to work in a pre-set and defined industrial or academic set up. Planned and informed guidance, mentoring, and hand-holding are required for graduate students to inculcate the passion for an enterprise. During their coursework, igniting a flame of entrepreneurship, motivating them to become their own boss and creating conducive environment to establish a business could significantly contribute to the socio-economic growth of a society. The well-coordinated efforts of industry heads, university professors, corporate associations, and governmental departments could bring about radical and far-reaching changes in setting-up industries by fresh bio-graduates. This case study throws light on how the existing system can modify its course work to achieve this goal and how an industry-academia-government alliance can play a significant role towards this initiative on entrepreneurship.

Published: December 2012

The unbundling of the electricity industry has changed the way the energy supply business is handled from a mainly technical to a more commercially dominated one. This new paradigm shift has facilitated creation of new system and/or market operation entities in electrical utilities throughout the world. The increasing number of different companies with diverse interest participating in the electricity supply business leads to a shift from traditional tasks of power system operation among these companies to new additional job duties or even a complete new job as system or market operator. This case study examines the critical change that have taken place in the commercial environment in which power system operators now work both at the system operation level as well as in the generation operation and how that affects their day-to-day operations. This case study analyses the international scenario along with their performance targets that have already been implemented worldwide and would describe their impacts on the job to be performed by the system operator in India. Finally the training needs of system and market operators’ personnel both at the system operation and generation operation where these entities are separated are pointed out, focusing on the new points that have arisen because of the new commercial environment.

Authors: Chang Jinn-Ming , Huang Pai-Jung , Gwo Chih-Ying , Li Yue , Wei Chia-Hung
Published: December 2012

In hospitals and medical institutes, a large number of mammograms are produced in ever increasing quantities and used for diagnostics and therapy. The need for effective methods to manage and retrieve those image resources has been actively pursued in the medical community. This paper proposes a hierarchical correlation calculation approach to content-based mammogram retrieval. In this approach, images are represented as a Gaussian pyramid with several reduced-resolution levels. A global search is first conducted to identify the optimal matching position, where the correlation between the query image and the target images in the database is maximal. Local search is performed in the region comprising the four child pixels at a higher resolution level to locate the position with maximal correlation at greater resolution. Finally, this position with the maximal correlation found at the finest resolution level is used as the image similarity measure for retrieving images. Experimental results have shown that this approach achieves 59% in precision and 54% in recall when the threshold of correlation is0.5.

Published: December 2012

Digital image authentication refers to all the techniques performing anti-falsification, digital image copyright protection, or access control. A large number of DIA techniques have been developed to authenticate digital images, including cryptography-based digital image authentication (CBDIA) techniques and data-hiding-based digital image authentication (DHBDIA) techniques. This paper not only provides some practical applications on image authentication, but also describes general frameworks of image watermarking and the general techniques, including robust watermarking, fragile watermarking, and semi-fragile watermarking. This paper also addresses the potential issues on future research directions, including managing the PRNU database, development of advanced PRNU-based blind authentication techniques, and search for digital fingerprints.
Decomposed PRNU Library for Forensics on Photos
Authors: Li Yue
Published: December 2012

Today, the digital forensic techniques for digital images are developed with the origin identification and integrity verification functions for security reasons. Methods based on photo-response-non-uniform (PRNU) are widely studied and proved to be effective to serve the forensic purposes. However, due to the interpolation noise, caused by the colour filtering and interpolation function the accuracy of the PRNU-based forensic method has been degraded. Meanwhile, the tremendous physical storage requirement and computation consumption limit the applications of PRNU-based method. Therefore, an innovative DPRNU-based forensic method has been proposed in order to solve the above problems. In the method, the artificial component and physical component are separated according to the colour filtering array (CFA) and the PRNU are only extracted from the physical component in order to remove the interference caused by the interpolation noise, which increases the accuracy of the camera identification and integrity verification. Meanwhile, due to the separation, the DPRNU are only 1/3 of the size of the traditional PRNU, which saves considerable physical storage in setting up the digital library and fasters the comparison speed between the fingerprints.
Agent Negotiation in Water Policy Planning
Authors: Lin Menq-Wen , Wei Chia-Hung , Cheng Pei-Cheng
Published: December 2012

With the growing demand for water, and many challenges related to water availability, food security, pollution, and environmental degradation, it becomes imperative to establish good water policy planning for a sufficient supply of water consumption. This paper presents a general problem-solving framework for modeling multi-issue agent negotiation in water policy planning via fuzzy constraint processing. All participants involved in water policy planning are modeled as agents. Agent negotiation is formulated as a distributed fuzzy constraint satisfaction problem. Fuzzy constraints are used to define each participant’s professional views and demands. The agent negotiation simulates the interactive process of all participants’ water policy planning. This approach provides a systematic method to reach an agreement that benefits all participants’ water policy planning with a high satisfaction degree of fuzzy constraints, and move towards the deal more quickly since their search focuses only on the feasible solution space. An example application to Negotiation for Water Policy Planning is considered to demonstrate the usefulness and effectiveness of the proposed approach.

Authors: Tella Adeyinka
Published: December 2012

Universities are investing heavily in electronic resources. As a way of embracing new developments, the University of Ilorin, Nigeria, has spent millions of dollars building a usable e-library. However, research indicates that potential users may still not use e-libraries. This study examines user acceptance of e-library from the perspective of technology acceptance mode (TAM). E-library system characteristics, organisational context, and individual characteristics are identified as variables that determine acceptance. Data was collected through self-designed questionnaire from 1,500 undergraduate users of the e-library. The findings revealed that the acceptance constructs, ease of use, perceived usefulness, actual use, satisfaction, relevance, awareness, computer/internet self-efficacy, and social influence, significantly correlate with e-library acceptance. The study suggests that all eight factors jointly pulled 69% prediction of the users’ acceptance of e-library. The study recommends that e-library users at the university increase their computer and internet self-efficacy, which significantly enhances their use of the e-library system. The university can assist in this matter by organising computer training for the students.

Authors: Sriraam N. , Vijayalakshmi S. , Suresh S.
Published: December 2012

Fetal heart biometry is an indicator for providing information about the presence of heart chambers, their growth, and well being. As a clinical routine, ultrasonic scanning based fetal biometry is performed during the second trimester by skilled specialists. Such procedures are often considered tedious and time consuming. Detection of congenital heart abnormalities, such as septal defects, affects the proper functioning of the heart during the growth of the fetus, and such defects can be identified if the fetal heart structure and its features like size, shape, and symmetry are monitored. Recently, attempts have been made to provide computer-aided automated procedure where the performance depends on the efficacy of the developed algorithms. This work focuses on computer aided automated fetal cardiac scanning using 2-D ultrasonic imaging from fetal heart biometry. The process involves extracting frames from the cine-loop sequences followed by removal of noise using morphological filters. The chamber region is recognized by introducing automated region of interest (ROI). Experimental simulation study demonstrates the efficiency of algorithm in detecting the shape of each chamber. The identified chamber shape will further facilitate in automated measurement of fetal heart chamber and thus reduces the qualitative visualization errors.

Recognition of Emotions in Gait Patterns Using Discrete Wavelet Transform
Authors: Khair N. M. , Muthusamy Hariharan , Yaacob S. , Basah S. N.
Published: December 2012

Emotion is a natural instinctive state of mind deriving from one’s circumstances, mood, or relationships with others. Emotion can be characterized primarily by the psycho-physiological expressions, biological reactions, body interaction, and mental states. The emotional component is to be important for social interaction to serve the communication, response, and conveying information. The problem in controlling and maintaining human emotion can lead to emotional disorder. According to the National Institute of Mental Health (NIMH), approximation of 10-15% of the children tend to have an emotional and behavioral disorder. In this paper, discrete wavelet transform (DWT) was proposed to recognize human emotions in gait patterns. Four discrete categories of emotion such as fear, happy, normal, and sad were analyzed. Data was extracted from a single stride of gait. Daubechies wavelet of order 1 and order 4 was utilized to investigate their performance in recognizing emotional expression in gait patterns. Six statistical features namely mean, maximum, minimum, standard deviation, skewness, and kurtosis were derived from both approximation and detail coefficients at every level of decomposition. The discrete emotion was classified using kNN and fkNN classifier. The maximum classification accuracy of 96.07% was obtained at the first level of decomposition using kNN.
A New Single Trial P300 Classification Method
Authors: Li Kun , Sankar Ravi , Cao Ke , Arbel Yael , Donchin Emanuel
Published: December 2012

P300-Speller is one of the most practical and widely used Brain Computer Interface (BCI) for locked-in people who are not able to communicate with others via traditional communication methods. Many signal processing techniques have been utilized in P300-Speller to restore the communication ability of these locked-in people. These techniques are capable of achieving high classification accuracy. However the classification accuracy dramatically decreases for single trial analysis. The reason for that is that the noises existing in the recorded signals are usually removed by averaging several trials. When only a single trial is available, averaging is no longer an option for de-noising. The “averaging” step becomes the bottle neck of P300 response detection which highly limits the processing speed. Researchers are looking for techniques that can accomplish the classification task in a single trial. In this work, a new, effective but simple processing technique for single trial electroencephalography (EEG) classification using variance analysis based method is presented. This method achieved an overall accuracy of 84.8% for single trial P300 response identification. When compared with a single trial stepwise linear discriminant analysis (SWLDA), the authors’ method in terms of overall accuracy is more accurate and the data communication speed is significantly improved.

Published: December 2012

The electrocardiogram (ECG) signal has often been reported to play an important role in the primary diagnosis, prognosis, and survival analysis of heart diseases. Electrocardiography has brought several valuable impacts on the practice of medicine. This paper deals with the feature extraction and automatic analysis of different ECG signal waves using derivative based/ Pan-Tompkins based algorithms. The ECG signal contains an important amount of information that can be exploited in different way. It allows for the analysis of cardiac health condition. The discrimination of ECG signals using the Data Mining Decision Tree techniques is of crucial importance in the cardiac disease therapy and control of cardiac arrhythmias. Different ECG signals from MIT/BIH Arrhythmia data base are used for ECG features extraction and analysis. Two pathologies are considered: atrial fibrillation and right bundle branch block. Some decision tree classification algorithms currently in use, including C4.5, Improved C4.5, CHAID (Chi square Automatic Interaction Detector) and Improved CHAID are performed for performance analysis. Promising results have been achieved using the C4.5 classifier, with an overall accuracy of 96.87%.

European Parliament Online
Authors: Vesnic-Alujevic Lucia
Published: December 2012

The objective of this paper is to chart the boundaries of the developing phenomenon of the use of information and communication technologies to support politics by large political organizations such as the European Parliament through the analysis of the online strategy of the European Parliament in its campaign for widening participation in the 2009 European Parliament elections. For the first time, during the electoral campaign, the European Parliament decided to lead its own campaign to raise awareness among citizens and increase turnout, and constructed its campaign on an official website and on five social network sites. The authors have concentrated on the European Parliament website, as well as on its profile on three most used social media sites: Facebook, Twitter, and YouTube. Since it is difficult to make a deeper comparison between these different online platforms, the authors have tested them on different communicative functions and campaign elements. Through the use of computer-mediated discourse analysis, this descriptive and explorative study has tried to discover the dynamics of the campaign, the reasons for choosing a specific platform for a particular part of the campaign, and the possibility of complementariness between them.
Satisfaction and Motivation
Authors: Hernández-López Adrián
Published: December 2012

Job satisfaction and motivation are traditional areas of organizational psychology research. Nevertheless, within Software Engineering (SE), these concepts continue to be in the research agenda. These concepts are interrelated between them and with other important management aspects within SE: productivity measurement. In this paper, the job satisfaction and the motivation of software development team members are analyzed using a qualitative exploratory approach. Results are presented under the point of view of Maslow’s hierarchy of needs and Herzberg’s dual factor theory. Moreover, the factors that participants considered as improvers of their productivity are also analyzed. And also, links between productivity factors and motivation are analyzed. Finally, results points to a high presence of hygienic factors that should be covered if organizations what to improve the job satisfaction of software project team workers.
Inspired Social Spider Behavior for Secure Wireless Sensor Networks

Last year’s biologically inspired systems had received a great interest. Behavior of social insects, DNA computation, artificial neural networks, evolutionary computation, and artificial immune systems are some of the interests which can be highlighted. Wireless sensor networks have no clear line of defense and no fixed infrastructure; therefore, the known security techniques used for cabled networks might not work perfectly. While wireless sensor networks, node misbehavior can cause the packet dropping, packet modification, packet misrouting, selfish node behavior, and so on. A biologically-inspired algorithm for detecting misbehaving nodes in a wireless sensor network is presented. Such an algorithm, inspired by the behavior of some social spiders from Congo, a specially their strategy to collaborate for detecting an intrusion in their web.
Myoepithelioma breast: Clinically masquerading as breast carcinoma

Pure myoepithelioma of breast is an extremely rare tumor. Only a few cases have been reported in the literature so far. A 30-year old female presented with a large fungating mass arising from the areolar region of her right breast of six months duration. A clinical diagnosis of breast carcinoma was made and a mastectomy was performed. The specimen measured 23×22×9 cm with attached skin, and showed a large white ulcerated growth with areas of necrosis and hemorrhage. No normal breast tissue, nipple or areolar region was seen. Histopathological examination showed oval to spindle cells arranged in fascicles and bundles with whorling pattern in places showing mild pleomorphism with oval to spindle-shaped vesicular nuclei, prominent eosinophilic nucleoli, eosinophilic cytoplasm and clear cell changes in places, along with perivascular hyalinization and collagenization. Differential diagnosis of pleomorphic hyalinizing angiectatic tumor, solitary fibrous tumor, perivascular epithelioid cell tumor, mammary type myofibroblastic tumor and myoepithelioma were all considered. Immunohistochemistry for vimentin, smooth muscle actin, calponin, caldesmon, p63, epithelial membrane antigen, S-100, CD-31, CD-34, muscle specific antigen, myogenin, desmin, and pancytokeratin was carried out. On the basis of positive staining for vimentin, actin, p63 (nuclear), calponin and caldesmon (focal), a final diagnosis of myoepithelioma was considered; however, cytokeratin negativity was an unusual finding. This case was considered worthy of documentation because of its rarity, and because it highlights the importance of proper clinical examination and radiological examination to prevent misdiagnosis.
Motifs Génériques
Authors: Déglise Frédéric
Published: December 2012

The aim of the article is to show that every mixed triangulated motive in the sense of V. Voevodsky determines a canonical cycle module in the sense of M. Rost. Our method consists of interpreting geometrically the axioms of cycle modules in a category of pro-motives called "generic motives". It is general enough to show at the same time that every cohomological theory which induces a realization of triangulated mixed motives defines a canonical cycle module. This is in particular applicable to De Rham and rigid cohomology.

Semitopological Homomorphisms
Authors: Giordano Bruno Anna
Published: December 2012

Inspired by an analogous result of Arnautov about isomorphisms, we prove that all continuous surjective homomorphisms of topological groups

f :G → H

can be obtained as restrictions of open continuous surjective homomorphisms

\tilde f : \tilde G → H

, where

G

is a topological subgroup of

\tilde G

. In case the topologies on

G

and

H

are Hausdorff and

H

is complete, we characterize continuous surjective homomorphisms

f : G → H

when

G

has to be a dense normal subgroup of

\tilde G

.

We consider the general case when

G

is requested to be a normal subgroup of

\tilde G

, that is when
f
is
semitopological
— Arnautov gave a characterization of semitopological isomorphisms internal to the groups

G

and

H

. In the case of homomorphisms we define new properties and consider particular cases in order to give similar internal conditions which are sufficient or necessary for

f

to be semitopological. Finally we establish a lot of stability properties of the class of all semitopological homomorphisms.
