Dual-Hop OSTBC Transmissions Over Fading Channels under Receiver Phase Noise for Regenerative Systems
Authors: Sujatha K. , Varadarajan S.
Published: December 2020

Space-time coding for fading channels is a Communication technique that realizes the diversity benefits of multiple transmit antennas. Previous work in this area has focused on the narrowband flat fading case where spatial diversity only is available. In this paper, we investigate the use of space-time coding in OFDM based broadband systems where both spatial and frequency diversity are available. We consider a strategy which basically consists of coding across OFDM tones and will therefore be called space-frequency coding. For a spatial broadband channel model taking into account physical propagation parameters and antenna spacing, we derive the design criteria for space-frequency codes and we show that space-time codes designed to achieve full spatial diversity in the narrowband case will in general not achieve full space-frequency diversity. Specifically, we show that the Alamouti scheme across tones fails to exploit frequency diversity. For a given set of propagation parameters and given antenna spacing, we establish the maximum achievable diversity order. Finally, we provide simulation results studying the influence of delay spread, propagation parameters, and antenna spacing on the performance of Space-frequency codes.

Authors: Khartad Ujwala D. , Krishna R. . K.
Published: December 2020

In recent years, the use of mobile ad hoc networks (MANETs) has been widespread in many applications, including some mission critical applications, and as such security has become one of the major concerns in MANETs. A mobile ad hoc network is set up with a group of mobile wireless nodes without the use of any dedicated routers or base stations. Each node acts as an end node as well as a router for other nodes. A Mobile Ad-hoc Network (MANET) is based on self organizing, dynamic structure and freedom of mobility idea. The characteristics like dynamic structure, limited power, restricted bandwidth and continuously changing network routes makes MANET more vulnerable to the attacks and providing the security to it proves to be a challenging area. In this paper, we describe that how the flooding attack occur and the effect of flooding attack. Finally, we present simulation results to show the detrimental effects of Flooding Attack.

India is world’s largest democracy. Fundamental right to vote or simply voting in elections forms the basis of Indian democracy. In India all earlier elections a voter used to cast his vote by using ballot paper. This is a long, time-consuming process
and very much prone to errors. This situation continued till election scene was completely changed by electronic voting machine. No more ballot paper, ballot boxes, stamping, etc. all this condensed into a simple box called ballot unit of the electronic voting machine. Cell phone based voting machine is capable of saving considerable printing stationery and transport of large volumes of electoral material. It is easy to transport, store, and maintain. It completely rules out the chance of invalid votes. Its use results in reduction of polling time, resulting in fewer problems in electoral preparations, law and order, candidates' expenditure, etc. and easy and accurate counting without any mischief at the counting Centre.
Mobile technology has attained heights and the market trend is such that every citizen of India possesses a mobile handset at cheaper rates of services. Even NRIs who long to cast votes can avail this advanced technology without taking the pain of coming to Polling booth with the help of their handy Mobile Equipment (ME). When such a Personal Digital Assistant (PDA) is available, why not using it for time-saving, cost- effective and secured method of voting??? The proposed paper is a collaboration of Computer
Networking with biometrics. In this paper, an electronic voting scheme using GSM based Mobile technology is presented. By integrating an electronic voting scheme with the Mobile infrastructure, we are able to exploit existing Secure Mobile authentication
mechanisms and provide enhanced voter authentication using Fingerprinting Technology (Biometrics) and mobility while maintaining voter privacy.
Superior mesenteric artery syndrome in conjunction with Crohn’s disease – a case report
Authors: Červinková Ivana , Pavlovská Denisa , Charvátová Marcelqa , Skotáková Jarmila
Published: December 2020

Superior mesenteric artery syndrome (SMAS) is a rare condition characterized by mechanical compression of the third part of the duodenum between the abdominal aorta and the superior mesenteric artery. The relationship between Crohn‘s disease and SMAS is seldom described in literature, although patients with Crohn‘s disease have many predispositions to its development. We describe the case of a 17-year- -old female patient who has been dia gnosed with Crohn‘s disease for several years and has been experiencing symptoms of abdominal discomfort and significant weight loss for five months. Magnetic resonance imaging was a key method for dia gnosing SMAS. In addition, older contrast computed tomography scans were evaluated retrospectively with regards to the aortomesenteric angle and distance, the reduction of which is a diagnostic criterion for SMAS. Our goal is to highlight the importance of measuring these values in patients with Crohn‘s disease for early detection of the risk of SMAS.

Published: December 2020

An acute abdomen is an urgent condition requiring rapid diagnosis and treatment. Nowadays, with the new developments and progression in ultrasonography (US) and computed tomography (CT), these methods have become a far better alternative to plain abdominal radiography. US is now an available and proven method used to provide a “final” diagnosis in various conditions. The frequency for CT examination for the diagnosis of acute abdomen has increased. A disadvantage of using CT examination includes high doses of radiation for the patient. Fortunately, this disadvantage is outweighed by the multitude of advantages. The advantages include high sensitivity and specificity in the detection of causes in urgent conditions. The CT protocol of examination is primarily lead by the radiologist.

La dialéctica de la melancolía en Søren Kierkegaard. Una aproximación al problema
Authors: Peña Arroyave Alejandro
Published: December 2020

El artículo presenta una aproximación al concepto de melancolía en las obras tempranas de Søren Kierkegaard. La hipótesis que se presenta consiste en que la melancolía es un fenómeno central en el proyecto de pensamiento de Kierke- gaard ya que está presente, en sus múltiples desarrollos, en todas las etapas o mo- mentos existenciales expuestos en la obra del pensador danés. En ese sentido, se presenta una lectura general del problema abarcando varias obras, para mostrar de qué modo hay cierta omnipresencia de la melancolía. Sin embargo, tomaremos a O lo uno o lo otro como la obra central para el abordaje del fenómeno. En primer lugar, se indaga por los múltiples significados de la melancolía en Kierkegaard, es decir, por el tipo o los diversos tipos de melancolía presentes en su obra. En segundo lugar, se indaga acerca del carácter ambiguo del fenómeno y, en último lugar, se presenta una lectura del concepto de melancolía en términos ontológicos, es decir, como algo constitutivo y constituyente de la existencia.

Este artículo indaga la noción de subjetividad lingüística propuesta por Levinas, la cual intenta ser una alternativa a la concepción moderna y occidental de sujeto. Dicha propuesta no busca fundamentar la subjetividad ni en el ser ni en el conocimiento, sino que inspecciona la responsabilidad, el decir originario y el diálogo en su estructura fundamental. Metodológicamente se analizan los textos levinasianos, en especial su obra De otro modo que ser o más allá de la esencia, concluyendo que su noción de sujeto inquieto, que es ruptura del reposo de la ontología y de la individualidad aislada, aporta a la cultura contemporánea una forma de expresar lo humano que respeta el dinamismo de la alteridad en la ipseidad, y hace posible la convivencia pacífica y la fraternidad.

Published: December 2020

Este trabajo presenta una estrategia de planificacón de trayectorias en equipos de robots moviles basada en el uso de modelos definidos con redes de Petri. Estos tipos de modelos son muy útiles para especificaciones de alto nivel ya que, en este caso, los métodos clásicos de planificación (funciones potenciales, algoritmos RRT, RRT*) no se pueden utilizar, siendo difícil determinar a priori la secuencia de configuraciones para cada robot. Este trabajo presenta la definición formal de la Red de Petri de Movimiento de Robots que se obtiene a partir de una partición del entorno en celdas. Utilizando la estructura de la red de Petri, en caso de especificaciones definidas como fórmulas Booleanas o fórmulas en lógica temporal lineal (LTL), se presentan diferentes problemas de optimización que se pueden utilizar para obtener trayectorias para los robots. La principal ventaja de los modelos basados en redes de Petri es su escalabilidad con respecto al número de robots. Ello permite resolver con eficiencia problemas de planificación de equipos con un número grande de robots. En la segunda parte del trabajo, se presentan algunas extensiones y resultados nuevos para la planificación distribuida en entornos desconocidos y con comunicaciones parciales entre los robots.

Introduction: Local and regional policies to guide the allocation of scarce critical care resources have been developed, but the views of prospective users are not understood. We sought to investigate the perspectives of Canadian acute care physicians toward triaging scarce critical care resources in the COVID-19 pandemic.Methods: We rapidly deployed a brief survey to Canadian emergency and critical care physicians in April 2020 to investigate current attitudes toward triaging scarce critical care resources and identify subsequent areas for improvement. Descriptive and between-group analyses along with thematic coding were used.Results: The survey was completed by 261 acute care physicians. Feelings of anxiety related to the pandemic were common (65 percent), as well as fears of psychological distress if required to triage scarce resources (77 percent). Only 49 percent of respondents felt confident in making resource allocation decisions. Both critical care and emergency physicians favored multidisciplinary teams over single physicians to allocate scarce critical care resources. Critical care physicians were supportive of decision making by teams not involved in patient care (3.4/5 versus 2.9/5 p = 0.04), whereas emergency physicians preferred to maintain their involvement in such decisions (3.4/5 versus 4.0/5 p = 0.007). Free text responses identified five themes for subsequent action including the need for further guidance on existing triage policies, ethical support in decision making, medicolegal protection, additional tools for therapeutic communications, and healthcare provider psychological support.Conclusion: There is an urgent need for collaboration between policymakers and frontline physicians to develop critical care resource triage policies that wholly consider the diversity of provider perspectives across practice environments.

This paper concentrates towards submerged processing of image so as to improve the picture quality. As the greater part of the pictures of seaward establishments, drinking water store and so forth are caught and examined physically by divers. And manual intervention in this regard is dangerous, costly, and time-consuming and yet does not often enable a full assessment. Hence camera based inspection is used to capture the images under water. Using cameras underwater poses major technological challenges. The objects in the submerged images are pale, difficult to sight and examine because the images of such environment loses the details of the object. The articles in the submerged pictures are swoon, hard to see and examine in light of the fact that the pictures of such condition loses the subtleties of the item. The submerged pictures typically experience the ill effects of non-uniform lighting, low difference, slant, obscures and lessened hues. Also, consequently in this examination work, a novel technique has been proposed for dealing with submerged picture slanting and obscuring if there should be an occurrence of unidirectional cyclic waves and roundabout waves to upgrade the perceivability of submerged pictures. The proposed work develops a geometrical model for image restoration from these distortions with good accuracy

Scientific and innovative society can be produced by giving priorities in Science, Technology, Engineering, and Mathematics (STEM) as emphasized by Malaysian Higher Education Blueprint (2015-2025). STEM need to be implemented at higher education because universities need to produce competent graduates to support economy growth and sustainable development. Learning STEM through Problem Based Learning might allow the undergraduates to become more enthusiastic when problem-based instruction is incorporated with STEM by implementing teamwork and problem-solving techniques to engage the first-year undergraduates fully with the learning. This study was conducted to investigate whether Integrated STEM Problem Based Learning module could enhance and retain the interest towards genetics concepts among first-year undergraduates. Topics in genetics was considered difficult not only to teach but also to learn. In this research, to overcome the genetic concepts learning difficulties, genetic related topics were chosen to introduce STEM through problem-based learning approach, which might help first-year undergraduates to acquire deep genetic content knowledge. This is very vital for the first-year undergraduates, as the knowledge gained in their first semester will be applied in the upcoming courses in their entire undergraduates’ programs of study. A Pre-Experimental research design with one group-posttest design was applied. A total of 50 participants who are first-year undergraduates from Faculty of Biology from one of the public universities in Malaysia were involved. The Genetics Interest Questionnaire used to study if the STEM Problem Based Learning module could enhance and retain the interest towards genetics concepts. The research has proven that Integrated STEM through problem-based learning approach could enhance and retains the interest in learning genetics concepts among first-year undergraduates.

Abstract. Cloud base height (CBH) is an important parameter for many applications such as aviation, climatology or solar irradiance nowcasting (forecasting for the next seconds to hours ahead). The latter application is of increasing importance to operate distribution grids as well as photovoltaic power plants, energy storage systems and flexible consumers. To nowcast solar irradiance, systems based on all-sky-imagers (ASIs), cameras monitoring the entire sky dome above their point of installation, have been demonstrated. Accurate knowledge of CBH is required to nowcast the spatial distribution of solar irradiance around the ASI's location at a resolution down to 5 m. Two ASIs located at a distance of usually less than 6 km can be combined into an ASI-pair to measure CBH. However, the accuracy of such systems is limited. We present and validate a method to measure CBH using a network of ASIs to enhance accuracy. To the best of our knowledge, this is the first method to measure CBH by a network of ASIs which is demonstrated experimentally. In this study, the deviations of 42 ASI-pairs are studied in comparison to a ceilometer and characterized by camera distance. The ASI-pairs are formed from seven ASIs and feature camera distances of 0.8...5.7 km. Each of the 21 ASI-tuples formed from seven ASIs yields two independent ASI-pairs as the ASI used as main and auxiliary camera respectively is swapped. Deviations found are compiled into conditional probabilities telling how probable it is to receive a certain reading of CBH from an ASI-pair given that true CBH takes on some specific value. Based on such statistical knowledge, in the inference the likeliest actual CBH is estimated from the readings of all 42 ASI-pairs. Based on the validation results, ASI-pairs with small camera distance (especially if

Abstract. An improved representation of the 3-D air motion and precipitation structure through forecast models and assimilation of observations is vital for improvements in weather forecasting capabilities. However, there is little independent data to properly validate a model forecast of precipitation structure when the underlying dynamics are evolving on short convective times scales. Using data from the JPL Ku/Ka-band Airborne Precipitation Radar (APR-2) and the 2-um Doppler Aerosol Wind (DAWN) lidar collected during the 2017 Convective Processes Experiment (CPEX), the NASA Unified Weather Research and Forecasting (WRF) Ensemble Data Assimilation System (EDAS) modeling system was used to quantify the impact of the high resolution, sparsely-sampled DAWN measurements on the analyzed variables and on the forecast when the DAWN winds were assimilated. Overall, the assimilation of the DAWN wind profiles had a discernible impact to the wind field and the evolution and timing of the 3-D precipitation structure. Analysis of individual variables revealed that the assimilation of the DAWN winds resulted in important and coherent modifications of the environment. It led to increase of the near surface convergence, temperature and water vapor, creating more favorable conditions for the development of convection exactly where it was observed (but not present in the control run). Comparison to APR-2 and observations by the Global Precipitation Measurement (GPM) satellite shows a much-improved forecast after the assimilation of the DAWN winds – development of precipitation where there was none, more organized precipitation where there was some, and a much more intense and organized cold pool, similar to the analysis of the dropsonde data. Onset of the vertical evolution of the precipitation showed similar radar-derived cloud top heights, but delayed in time. While this investigation was limited to a single CPEX flight date, the investigation design is appropriate for further investigation of the impact of airborne Doppler wind lidar observations upon short-term convective precipitation forecasts.

Abstract. Flood events are the most frequent cause of damage to infrastructure compared to any other natural hazard, and global changes (climate, socio-economic, technological) are likely to increase this damage. Transportation infrastructure systems are responsible for moving people, goods and services, and ensuring connection within and among urban areas. A failed link in this system can impact the community by threatening evacuation capability, recovery operations and the overall economy. Bridges are critical links in the wider urban system since they are associated with little redundancy and a high (re)construction cost. Riverine bridges are particularly prone to failure during flood events; in fact, the risks to bridges from high river flows and bank erosion have been recognized as crucial at global level. The interaction among flow, structure and network is complex, and yet to be fully understood. This study aims to establish rigorous practices of Computational Fluid Dynamics (CFD) for modelling hydrodynamic forces on inundated bridges, and understanding the consequences of such impact on the surrounding network. Objectives of this study are to model hydrodynamic forces as demand on the bridge structure, to advance a reliability analysis of the structure under the modelled loading and to assess the overall impact at systemic level. The flood-prone City of Carlisle (UK) is used as case study and a proof of concept. Implications of the hydrodynamic impact on the performance and functionality of the surrounding transport network are discussed. This research will help to fill the gap between current guidance for design and assessment of bridges within the overall transport system.

Abstract. Due to its micron-scale resolution and micro-destructiveness, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is especially suited for exploring closely spaced layers in the oldest and highly thinned sections of polar ice cores. Recent adaptions of the LA-ICP-MS technique have achieved fast washout times as the basis for introducing state-of-the-art 2D imaging to ice core analysis. This new method has great potential in its application for investigating the localization of impurities on the ice sample, crucial to avoid misinterpretation of ultra-fine resolution signals. Here first results are presented from applying LA-ICP-MS elemental imaging to selected glacial and interglacial samples of the Talos Dome and EPICA Dome C ice cores from central Antarctica. The localization of impurities with both marine and terrestrial sources is discussed, revealing generally a strong connection with the network of grain boundaries but also distinct differences among climatic periods. Scale-dependent image analysis shows that the spatial significance of a single line profile along the main core axis increases systematically as the imprint of grain boundaries weakens. With this, it is demonstrated how instrumental settings can be adapted specifically fit-for-purpose, i.e. either to employ LA-ICP-MS to study the impurity-microstructure interplay or to investigate highly thinned climate proxy signals in deep polar ice.

In facing business competition in the cement industry, PT Semen Baturaja (Persero) Tbk is making creative and innovative breakthroughs. Poor procurement planning, competence in the procurement of goods and services, hard skills and soft skills, ineffective coordination between divisions, low culture and work discipline, as well as ineffective education and training are the main causes of the ineffective implementation of the e-Procurement system in the company. Employee performance in the e-procurement division is a concern in this study. This study aims to determine the influence of competence, education, training, and employee placement partially and simultaneously on employee performance at PT. Semen Baturaja (Persero) Tbk. This study uses a quantitative approach with a confirmative survey method that is descriptive and uses verification. The population and sample of this study is all employees in e-procurement division, as it uses a census sampling technique, amounting to 105 respondents. The data is gathered using questionnaire, documentation, and observation method. Furthermore, the data is then processed using SPSS 24 application. The results of this study show that employee competence, education, training, and employee placement had positive effects on employee performance. The strategy to improve employee performance will be effective by first providing technical training to improve competence in the e-Procurement division, then rearranging the placement by paying more attention to the suitability of individual competencies, expertise, and abilities in carrying out the e-Procurement Standard Operating Procedure.
The Question of the “Divine Status” of the Davidic Messiah
Authors: Zehnder Markus
Published: December 2020

This article addresses the question whether there are compelling reasons that suggest that the Davidic messiah in the Hebrew Bible must be a divine being, as opposed to having merely a human-heroic status. It presents a number of arguments that support a divine understanding in some of the texts that can be related to the expectation of a future Davidic messiah. It also draws attention to the fact that in many instances the divine interpretation of the relevant texts is possible or likely rather than necessary and that it is only the combination of a number of suggestive passages that allow the reader to discern the divine character of the Davidic messiah. The investigation is located in the broader context of the question of monotheism in the Hebrew Bible and draws some conclusions concerning the theological consequences of the affirmation of the divinity of the Davidic messiah.
Onomastics and Numerical Composition in the Genealogy of Matthew
Authors: Bryan Steven M.
Published: December 2020

It has long been speculated that Matthew made use of the numerical values of the Hebrew letters of David’s name in structuring his genealogy. This article proposes criteria for discerning numerical composition and shows that Matthew sees numerical significance not just in the name David but in each of the key figures that fall at the junctures of the genealogy: Abraham—David—Jeconiah—messiah. These are the genealogical terms that evoke the themes that Matthew will develop in narrating the identity of Jesus and his messianic people. To highlight these four figures, Matthew has calculated the numerical values of all the names in his list, using a discernible rationale to adjust a handful of names. The literary effect he achieves imbues the 3 × 14 scheme with a heightened sense of divine purpose.
Scarecrows and Scapegoats: The Futility and Power of Cleaning a Landscape
Authors: Betz-Heinemann Khalil Avi , Tzanopoulos Joseph
Published: December 2020

This paper investigates why the culling of corvids in Northern Cyprus continues despite it being recognised by those that do it as ineffective. Participant observation, semi-structured interviews and archival research were conducted with a range of people involved in the management and practice of culling. The analysis shows that the introduction of the ruined landscape narrative to Cyprus during the era of British colonialism established a division between civilized and uncivilized, clean, and dirty behaviours amongst nonhuman animals. This relationship has been carried through into contemporary wildlife management by organisations involved in hunting who seek to maintain a clean hunting landscape through culling. However, it is argued here that this culling is futile and there is a disconnect between the effectiveness of the management of the landscape and what hunters are witnessing during hunting. Nonetheless, it continues because the cleaning of corvids as administratively recorded waste demonstrates the organisations’ and their administrative medium’s power and control over the landscape.
