A Prototype Curriculum For The Study Of Software Management

The discipline of Software Management, which is a new and potentially meaningful direction for information technology (IT) education, is presented for the first time in this article.  Software Management is a curriculum model, which specifically addresses the productivity and quality issues that have arisen in IT.  It is distinguished from the traditional disciplines of Computer Science, Software Engineering and Information Science by its body of knowledge, which focuses explicitly on building strategic governance infrastructures rather than technical artifacts.  This article presents curricular recommendations for each traditional discipline and uses these to illustrate Software Management’s unique role and value.  It also presents a conceptual framework and justification, which will assist educators in curriculum development and design issues

Navigating The Leading Edge: A Prototype Curriculum for Software Systems Management

This article presents a meaningful and advantageous new direction for information technology education, embodying principles for systematically optimizing the functioning of the business. Our curriculum was built on the thesis that every aspect of software systems management can be understood and described as a component of four universal, highly correlated behaviors: abstraction, product creation, product verification and validation, and process optimization. Given this, our model curriculum was structured to provide the maximum exposure to current best practice in six thematic areas, which taken together as an integrated set, makes-up the attributes that differentiate us from the other computer disciplines: Abstraction: understanding and description of the problem space Design: models for framing artifact to meet criteria 3, 4, 5, and 6 Process Engineering: application of large models such as IEEE 12207 Organizational Control Systems: SQA and configuration management Evaluation with Measurement: with an emphasis on testing and metrics Construction: professional programming languages with emphasis on reusability Our teaching strategy approaches this as a hierarchy of similar activities. In every course we require the student to define and implement all three interfaces and be able to clearly communicate this as a logically consistent model before working out the details of the solution. The focus of all understanding is top-down from the information interface. Our curriculum centers on the application of software engineering standards (such as those promulgated by IEEE) and the software process improvement, or quality standards (such as those promulgated by SEI and ISO) under the assumption that this embodies the common body of knowledge and state of best practice in software production and management. The practical realization of this is an integration of the large subject areas of: software engineering (methods, models and criteria), process and product quality management (software quality assurance and metrics), software project management (work decomposition, planning, sizing and estimating), and software configuration management. Reconciliation of project and configuration management is accomplished by cross-referencing the problems, tools, notations and solutions (through explicit identification, authorization and validation procedures). As a side agenda, we have also stressed the need for re-engineering the vast number of software products currently on the shelves. This model plus germane simulated real-world experience introduces all of the relevant principles to the student within the (currently understood) framework. It allows them to develop and internalize their own comprehensive understanding and formulate a personal model of the disciplinary body of knowledge

Embedding Security Functionality In Formal Specifications Of Requirements

The methodology in this paper will let designers specify the security properties defined through the functional families of the ISO/IEC 15408 Standard, graphic representations.  This blueprint will allow both business and technical participants, to discuss and refine a common solution.  It also serves as a roadmap, to guide the implementation process. We feel this can become a useful supporting methodology for the construction of effective security responses, because it ensures both the widest possible participation in the design process as well as the greatest degree of understanding.  The fact that the advice of the world’s experts is readily available and easy to use as a result of this process might also serve to make the mission to protect America’s information assets a little more effective

Chlorido(η 4-cyclo­octa-1,5-diene)(N,N′-diethyl­thio­urea-κS)rhodium(I)

In the title rhodium(I) complex, [RhCl(C8H12)(C5H12N2S)], N,N′-diethyl­thio­urea acts as a monodenate S-donor ligand. The rhodium(I) coordination sphere is completed by the Cl atom and the COD [= 1,5-cyclo­octa­diene] ligand inter­acting through the π-electrons of the double bonds. If the midpoints of these two bonds are taken into account, the Rh atom exhibits a distorted square-planar coordination. The syn conformation of the N,N′-diethyl­thio­urea ligand with respect to the Cl atom is stabilized by an intra­molecular N—H⋯Cl hydrogen bond. A weak inter­molecular N—H⋯Cl inter­action links mol­ecules along the a axis

Threat Modeling the Enterprise

Current threat modeling methodologies and tools are biased toward systems under development. While, organizations whose IT portfolio is made up of a large number of legacy systems, that run on fundamentally different and incongruous platforms and with little or no documentation, are left with few options. Rational, objective analysis of threats to assets and exploitable vulnerabilities requires, the portfolio to be represented in a consistent and understandable way based on a systematic, prescriptive, collaborative process that is usable but not burdensome. This paper describes a way to represent an IT portfolio from a security perspective using UML deployment diagrams and, subsequently, a process for threat modeling within that portfolio. To accomplish this, the UML deployment diagram was extended, a template created, and a process defined

Evaluating Return On Investment For Software Process Improvement Projects

This article presents a simple approach that will allow decision-makers to evaluate the return on investment of software process improvement prior to launching such an effort. Obviously, it will be easy to tell ten years up the road whether the right decision was made. But a CEO, or CIO contemplating laying out six, or seven figures for the additional personnel and resources to conduct SPI is not in a position to make that call and the wise ones will not be led into it by blind faith. The problem is assessing the risks and returns of such a project in terms and perspective that a non-technical decision-maker can understand. We believe our instrument serves that purpose

Benefits of battery hybridization in hydraulic turbines. Wear and tear evaluation in a Kaplan prototype

Kaplan turbines are nowadays used to provide Frequency Containment Reserve (FCR) to the grid due to their fast capacity to regulate their power maintaining high efficiency. However, this continuous power regulation increases the wear and tear of the regulation system considerably. To reduce the amount of movements in the regulation servomotors, and thus their wear and tear, a new technology is being investigated within the frame of the European project XFLEX Hydro. This new technology is based on hybridizing the hydro unit with a small size battery in parallel, this one being in charge of compensating the small frequency fluctuations in the grid by providing or absorbing power. In this paper, the benefits of the implementation of this new technology are evaluated. A Kaplan turbine prototype located in Vogelgrun, France, has been hybridized and different parameters have been monitored while the unit was working in hybrid mode and in normal standalone hydro mode. Wear and tear of the regulation system have been compared for both hybrid and standalone hydro modes. A reduction of about 25% in servomotors mileage and of 50% in fatigue damage have been obtained by hybridizing the unit.Peer ReviewedPostprint (published version

Gold Derivatives Development as Prospective Anticancer Drugs for Breast Cancer Treatment

Commonly used anticancer drugs are cisplatin and other platinum‐based drugs. However, the use of these drugs in chemotherapy causes numerous side effects and the onset of frequent drug resistance phenomena. This review summarizes the most recent results on the gold derivatives used for their significant inhibitory effects on the in vitro proliferation of breast cancer cell models and for the consequences deriving from morphological changes in the same cells. In particular, the study discusses the antitumor activity of gold nanoparticles, gold (I) and (III) compounds, gold complexes and carbene‐based gold complexes, compared with cisplatin. The results of screening studies of cytotoxicity and antitumor activity for the gold derivatives show that the death of cancer cells can occur intrinsically by apoptosis. Recent research has shown that gold (III) compounds with square planar geometries, such as that of cisplatin, can intercalate the DNA and provide novel anticancer agents. The gold derivatives described can make an important contribution to expanding the knowledge of medicinal bioorganometallic chemistry and broadening the range of anticancer agents available, offering improved characteristics, such as increased activity and/or selectivity, and paving the way for further discoveries and applications

Assessment of Power Swings in Hydropower Plants through High-Order Modelling and Eigenanalysis

Power plants are subject to introduce disturbances in the power grid, resulting from interactions with the dynamical behavior of the energy source subsystem. In the case of hydropower plants when used to compensate for variations of power generation and consumption, instabilities or undesirable disturbances may arise. They may be caused by phenomena such as part load vortex rope pulsations in the draft tube of Francis turbines. This may affect the dynamical behavior of the power plant and lead to troublesome interactions with the grid. This paper presents a case study of an existing hydropower plant that illustrates the effects of pressure pulsations due to vortex rope precession on the draft tube of Francis turbines. It also showcases possible solutions to the mitigation of the effects of this disturbing hydraulic phenomenon over the operation of the generators and electrical system. The investigated system is a 1 GW hydropower plant (4 x 250 MW units). The assessment of the power swings is performed through modal analysis combined with frequency-domain and time-domain simulations, which are then compared with on-site measurements
