Design of Power Systems Stabilizers for distributed synchronous generators using Linear Matrix Inequality solvers

The objective of this research is to evaluate the performance of a Power System Stabilizers (PSS), designed using a formulation based on Linear Matrix Inequalities (LMIs), in an Electric Power Distribution System (EPDS) with distributed synchronous generators operating under unbalanced three-phase. Under these conditions, the steady-state operation of the EPDS is not an equilibrium point, which introduces a new condition not covered by typical PSS design techniques. To overcome this problem, an EPDS modeling technique developed on a previous work by the authors research group was used. For the PSS design, a technique called V-K iteration was employed and the maximization of the minimum damping was set as the controller design objective. Furthermore, three LMI solvers were used (and compared) to assess design feasibility. A total of 880 operating points (for which the open loop minimum damping was smaller than 3%) were considered for the design. The results show that the proposed formulation is feasible and good controller performances can be achieved by the different PSSs designed using each of the tested LMI solvers.
FORTALECIMIENTO DE LA GOBERNANZA TRANS- FRONTERIZA EN AMÉRICA LATINA A TRAVÉS DE LA COOPERACIÓN DESCENTRALIZADA: LA EXPERIEN- CIA DEL PROGRAMA FRONTERAS ABIERTAS 1 Strengthening cross-border governance in Latin America through decentralized cooperation: the experience of the "open borders" program

La descentralización y la dimensión territorial del desarrollo han pasado a formar parte importante de la agenda política de muchos países latinoamericanos en los últimos años. Estos temas también han sido objeto prioritario de estudio en la Unión Europea y han constituido un factor fundamental en el proceso de integración europea. El rol de los actores locales y subnacionales en el proceso de integración se ha consolidado gracias, en buena medida, a la experiencia adquirida en la gestión del desarrollo de sus territorios y de las experiencias de cooperación transfronteriza. Esta experiencia ha permitido a las autoridades locales y regionales europeas convertirse en interlocutores cualifi cados para proyectar internacionalmente sus territorios a través de la cooperación descentralizada. El programa de la cooperación italiana Fronteras Abiertas pone en sinergia los elementos mencionados y pretende fortalecer el proceso de integración a través de la construcción de una red interregional de actores subnacionales para la cooperación transfronteriza en algunas áreas de América Latina, con el apoyo de la cooperación descentralizada italiana.
Boustrophedon coverage path planning for UAV aerial surveys in wind

In the quickly developing world of precision agriculture UAV remote sensing, there is a need for a greater understanding of winds effect on fixed wing aerial surveying, as this is missing from current literature. This paper presents a method to define and calculate flight times in a Boustrophedon aerial survey coverage path in wind, for a given convex polygon, at a given sweep angle. It is shown that there exists no easy way to define a sweep angle relative to the wind that minimises flight time. This method is validated by comparing the numerical simulated path and times with a number of surveys run in the high fidelity X-Plane simulator.
Safety and Efficacy of High-Dose Adenosine-Induced Asystole during Endovascular AAA Repair

Purpose: To assess the safety and efficacy of high-dose adenosine administration to increase the precision of endovascular abdominal aortic aneurysm (AAA) repair using a balloon deployed stent-graft. Methods: From January 1997 to March 1999, 98 AAA patients (79 men; mean age 71 years, range 62–91) were treated with balloon-expandable stent-grafts under an approved protocol. After placing a temporary transvenous ventricular lead or an external transthoracic pacing electrode, adenosine (24 mg initially) was administered in an escalating dose fashion to induce at least 10 seconds of asystole, during which the proximal stent was expanded. Results: Adenosine dosages ranged from 24 to 90 mg (median 24 mg). Nine (9.2%) self-limiting cardiac events were observed: 2 (2.0%) episodes of transient myocardial ischemia, 2 (2.0%) cases of atrial fibrillation requiring cardioversion, 1 (1.0%) transient left bundle branch block lasting <10 seconds, and 4 (4.1%) prolonged periods of asystole requiring temporary pacemaker activation. There were no cases of bronchospasm or worsening obstructive pulmonary disease, and no patients required inotropic support after adenosine-induced asystole. Conclusions: Cardiac events following adenosine-induced asystole are infrequent, mild, and easily treated. The perioperative use of high-dose adenosine to ensure precise stent-graft placement appears to be a safe method of inducing temporary asystole during endovascular aortic repair.
Location beats pedicle in laparoscopic partial nephrectomy

1 Urology Department, Satu-Mare County Hospital, Satu-Mare, Romania 2 Urology Department, University of Medicine and Pharmacy “Iuliu Hatieganu”, Cluj-Napoca, Romania 3 Urology Department, Clinical Municipal Hospital, Cluj-Napoca, Romania *Corresponding Author’s E-mail: drnicolaecrisan@gmail.com Tel. : +40 742 059 395 **This author had similar contributions as the main author Laparoscopic partial nephrectomy can be performed either by transperitoneal or retroperitoneal approach, both with specific advantages and drawbacks in terms of working space and peri-operative outcomes. The choice for the surgical approach is determined by the experience of the surgeon, the renal pedicle and tumor location – anterior tumors with single renal artery being thought to be more suitable for transperitoneal approach, and posterior tumors with multiple renal arteries for retroperitoneal approach. We analyzed 40 patients with anterior renal tumors and multiple arteries, which were randomly assigned to transperitoneal or retroperitoneal approach. We observed that transperitoneal approach associates a longer time for pedicle dissection in comparison with retroperitoneal approach, but a shorter tumor excision and renorraphy times. In conclusion, we consider that the transperitoneal approach ensures improved ergonomy for performing the excision and reconstruction steps of the partial nephrectomy, which impact the warm ischaemia time, thus the choice for the surgical approach should be based mainly on tumor location.
Changing concepts in long-term central venous access: catheter selection and cost savings.

BACKGROUND AND OBJECTIVES Long-term central venous access is becoming an increasingly important component of health care today. Long-term central venous access is important therapeutically for a multitude of reasons, including the administration of chemotherapy, antibiotics, and total parenteral nutrition. Central venous access can be established in a variety of ways varying from catheters inserted at the bedside to surgically placed ports. Furthermore, in an effort to control costs, many traditionally inpatient therapies have moved to an outpatient setting. This raises many questions regarding catheter selection. Which catheter will result in the best outcome at the least cost? It has become apparent in our hospital that traditionally placed surgical catheters (ie, Hickmans and central venous ports) may no longer be the only options. The objective of this study was to explore the various modalities for establishing central venous access comparing indications, costs, and complications to guide the clinician in choosing the appropriate catheter with the best outcome at the least cost. METHODS We evaluated our institution's central venous catheter use during a 3-year period from 1995 through 1997. Data was obtained retrospectively through chart review. In addition to demographic data, specific information regarding catheter type, placement technique, indications, complications, and catheter history were recorded. Cost data were obtained from several departments including surgery, radiology, nursing, anesthesia, pharmacy, and the hospital purchasing department. RESULTS During a 30-month period, 684 attempted central venous catheter insertions were identified, including 126 surgically placed central venous catheters, 264 peripherally inserted central catheters by the nursing service, and 294 radiologically inserted peripheral ports. Overall complications were rare but tended to be more severe in the surgical group. Relative cost differences between the groups were significant. Charges for peripherally inserted central catheters were $401 per procedure, compared with $3870 for radiologically placed peripheral ports and $3532 to $4296 for surgically placed catheters. CONCLUSIONS Traditional surgically placed central catheters are increasingly being replaced by peripherally inserted central venous access devices. Significant cost savings and fewer severe complications can be realized by preferential use of peripherally inserted central catheters when clinically indicated. Cost savings may not be as significant when comparing radiologically placed versus surgically placed catheters. However, significant cost savings and fewer severe complications are associated with peripheral central venous access versus the surgical or radiologic approach.

Distributed adaptive coordinated tracking for coupled nonholonomic mobile robots

In this paper, a coordinated tracking control problem is studied for coupled nonholonomic mobile robots with limited information of a reference trajectory. A distributed control law with adaptive time-varying gains is proposed to guarantee that the robots can form a prespecified geometric pattern while the centroid of the geometric pattern can track the reference signal. By designing the adaptive control gains, the control algorithm of this paper does not require the global knowledge of the upper bound on the leader's control input. The stability of the system is proved with the aid of Lyapunov techniques. Finally, a simulation example is presented to verify the theoretical results.
The State of Public Private Partnerships - The State and Public Private Partnerships ¤

This paper outlines the debates concerning the increasing popularity of the Public-Private-Partnership (PPPs) option as a viable strategy in a variety of both developed and developing countries. The essence of this contribution argues for a proper understanding of what PPPs are, what they can do, what their limitations are and what preconditions could help in their implementation. The broad theme of the paper concludes that, even though they may pay an integral developmental role, under certain circumstances and in certain sectors, one outht to be sanguine about these possibilities. To have any chance of success, PPPs require a new (and not necessarily diminished) set of responsibilities regarding the role of the State.
An efficient method for checking the integrity of data in the Cloud

Cloud computing and storage services allow clients to move their data center and applications to centralized large data centers and thus avoid the burden of local data storage and maintenance. However, this poses new challenges related to creating secure and reliable data storage over unreliable service providers. In this study, we address the problem of ensuring the integrity of data storage in cloud computing. In particular, we consider methods for reducing the burden of generating a constant amount of metadata at the client side. By exploiting some good attributes of the bilinear group, we can devise a simple and efficient audit service for public verification of untrusted and outsourced storage, which can be important for achieving widespread deployment of cloud computing. Whereas many prior studies on ensuring remote data integrity did not consider the burden of generating verification metadata at the client side, the objective of this study is to resolve this issue. Moreover, our scheme also supports data dynamics and public verifiability. Extensive security and performance analysis shows that the proposed scheme is highly efficient and provably secure.
Analysis of mtDNA variation in African populations reveals the most ancient of all human continent-specific haplogroups.

mtDNA sequence variation was examined in 140 Africans, including Pygmies from Zaire and Central African Republic (C.A.R.) and Mandenkalu, Wolof, and Pular from Senegal. More than 76% of the African mtDNAs (100% of the Pygmies and 67.3% of the Senegalese) formed one major mtDNA cluster (haplogroup L) defined by an African-specific HpaI site gain at nucleotide pair (np) 3592. Additional mutations subdivided haplogroup L into two subhaplogroups, each encompassing both Pygmy and Senegalese mtDNAs. A novel 12-bp homoplasmic insertion in the intergenic region between tRNA(Tyr) and cytochrome oxidase I (COI) genes was also observed in 17.6% of the Pygmies from C.A. R. This insertion is one of the largest observed in human mtDNAs. Another 25% of the Pygmy mtDNAs harbored a 9-bp deletion between the cytochrome oxidase II (COII) and tRNA(Lys) genes, a length polymorphism previously reported in non-African populations. In addition to haplogroup L, other haplogroups were observed in the Senegalese. These haplogroups were more similar to those observed in Europeans and Asians than to haplogroup L mtDNAs, suggesting that the African mtDNAs without the HpaI np 3592 site could be the ancestral types from which European and Asian mtDNAs were derived. Comparison of the intrapopulation sequence divergence in African and non-African populations confirms that African populations exhibit the largest extent of mtDNA variation, a result that further supports the hypothesis that Africans represent the most ancient human group and that all modern humans have a common and recent African origin. The age of the total African variation was estimated to be 101,000-133,000 years before present (YBP), while the age of haplogroup L was estimated at 98,000-130,000 YBP. These values substantially exceed the ages of all Asian- and European-specific mtDNA haplogroups.
Business Analytics Education: A Latent Semantic Analysis of Skills, Knowledge and Abilities Required for Business versus Non-Business Graduates

Market demand for business analytics (BA) professionals has been skyrocketing in recent years, but challenges arise in developing BA programs. In this study, we seek to uncover the key components of skills, knowledge, and abilities (SKAs) that employers require for this emerging profession by business degree and non-business degree (e.g., computer science, engineering, statistics, mathematics). We used Latent Semantic Analysis (LSA), a text mining technique, to analyze text data of BA position dvertisement on LinkedIn, and adopted the educational framework of Bloom’s taxonomy as a sensitizing lens to interpret our results. Our analysis reveals differences in the SKAs for different education: Business graduates are expected to have SKAs in mathematics and BI technologies, while CESM graduates are desired to have business strategy and market knowledge. KSAs are also identified for BA positions that are open to any other academic degrees. Implications on BA program and curriculum design are discussed.

Factors associated with successful arteriovenous malformation radiosurgery.

OBJECTIVE To analyze the clinical and angiographic variables that affect the results of arteriovenous malformation (AVM) radiosurgery and to propose a new method of reporting patient outcomes after AVM radiosurgery. This method incorporates both the obliteration status of the AVMs and the postoperative neurological condition of the patient. METHODS Patient outcomes were defined as excellent (nidus obliteration and no new deficits), good (nidus obliteration with a new minor deficit), fair (nidus obliteration with a new major deficit), unchanged (incomplete nidus obliteration without a new deficit), poor (incomplete nidus obliteration with any new deficit), and dead. Two hundred twenty patients who underwent AVM radiosurgery at our center before 1992 were subjected to a multivariate analysis with patient outcomes as the dependent variable. RESULTS Multivariate analysis determined four factors associated with successful AVM radiosurgery: smaller AVM volume (P=0.003), number of draining veins (P=0.001), younger patient age (P=0.0003), and hemispheric AVM location (P=0.002). Preradiosurgical embolization was a negative predictor of successful AVM radiosurgery (P=0.02). CONCLUSION AVM obliteration without new neurological deficits can be achieved in at least 80% of patients with small volume, hemispheric AVMs after single-session AVM radiosurgery. Future studies on AVM radiosurgery should report patient outcomes in a fashion that incorporates all the factors involved in successful AVM radiosurgery.
CGP 41251, a New Potential Anticancer Drug, Improves Contractility of Rat Isolated Cardiac Muscle Subjected to Hypoxia

&NA; The aim of the present work was to examine the effects of 4′‐Nbenzoyl staurosporine (CGP 41251), a protein kinase C inhibitor with broad antiproliferative activity in many cell lines, on the rat isolated heart contractility under normoxic and hypoxic conditions. Additionally, we examined the effects of CGP 41251, WB‐4101 (&agr;1a ‐adrenoceptor antagonist), chloroethylclonidine (CEC) (&agr;1b‐adrenoceptor antagonist) and selective damage of endocardial endothelium by Triton X‐100 on the protection against hypoxia induced by preconditioning of rat heart tissue. Experiments were performed on rat isolated left ventricular papillary muscle. The following parameters were measured: force of contraction (Fc), velocity of contraction (+dF/dt) and velocity of relaxation (‐dF/dt). The temperature of the bath solution was 37°C ± 0.5°C, and rate of electrical stimulation was 0.5 Hz. At concentrations less than 1&mgr;M CGP 41251 did not cause any changes in contractility of rat heart. At 1 and 3 &mgr;M, significant positive inotropic action was observed. Treatment of rat papillary muscle by CGP 41251 at 3 &mgr;M reduced decreasing of contractility by simulated hypoxia and reperfusion. Moreover, protective effects of preconditioning was not affected by addition of CGP 41251 neither at 1 nor at 3 &mgr;M. Pretreatment with CEC at 3 &Mgr;M, and selective damage of endocardial endothelium induced by fast (1‐s) immersion of papillary muscle in 0.5% Triton X‐100, but not pretreatment with WB‐4101, abolished the protective effects of preconditioning. The results imply that CGP 41251 improves contractility of heart muscle under normoxic and hypoxic conditions, and does not alter hypoxic preconditioning in rat isolated cardiac tissue. Moreover, it was shown that &agr;1b‐adrenoceptors and endocardial endothelium are involved in triggering of preconditioning in rat isolated heart muscle.
‘It's not the form; it's the process’: a phenomenological study on the use of creative professional development workshops to improve teamwork and communication skills

Introduction Past research has demonstrated the positive effects of visual and performing arts on health professionals' observational acuity and associated diagnostic skills, well-being and professional identity. However, to date, the use of arts for the development of non-technical skills, such as teamwork and communication, has not been studied thoroughly. Methods In partnership with a community print and media arts organisation, Centre[3], we used a phenomenological approach to explore front-line mental health and social service workers' experiences with a creative professional development workshop based on the visual and performing arts. Through preworkshop and postworkshop interviews with participants and postworkshop interviews with their managers, we sought to examine how participants' perceptions of the workshop compared with their preworkshop expectations, specific impacts of the workshop with respect to participants' teamwork and communication skills and changes in their perceptions regarding the use of the arts in professional development. Results Our workshops were successful in enhancing teamwork skills among participants and showed promise in the development of communication skills, though observable changes in workplace communication could not be confirmed. The workshop facilitated teamwork and collegiality between colleagues, creating a more enjoyable and accepting work environment. The workshops also helped participants identify the strengths and weaknesses of their communication skills, made them more comfortable with different communication styles and provided them with strategies to enhance their communication skills. Conclusions Participation in the arts can be beneficial for the development of interpersonal skills such as teamwork and communication among health professionals.
Utility of Milk Coagulant Enzyme of Moringa oleifera Seed in Cheese Production from Soy and Skim Milks

In this study, the potential use of Moringa oleifera as a clotting agent of different types of milk (whole, skim, and soy milk) was investigated. M. oleifera seed extract showed high milk-clotting activity followed by flower extract. Specific clotting activity of seed extract was 200 times higher than that of flower extract. Seed extract is composed by four main protein bands (43.6, 32.2, 19.4, and 16.3 kDa). Caseinolytic activity assessed by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and tyrosine quantification, showed a high extent of casein degradation using M. oleifera seed extract. Milk soy cheese was soft and creamy, while skim milk cheese was hard and crumbly. According to these results, it is concluded that seed extract of M. oleifera generates suitable milk clotting activity for cheesemaking. To our knowledge, this study is the first to report comparative data of M. oleifera milk clotting activity between different types of soy milk.
