José Manuel Rodríguez Gordillo, historiador y colaborador con investigadores histórico-contables

José Manuel Rodríguez Gordillo, profesor de Historia Moderna de la Universidad de Sevilla y Director del Archivo Histórico de la Fábrica de Tabacos de Sevilla falleció hace casi dos años. Fue una persona afable y enamorada de la investigación histórica sobre el tabaco.

En su etapa de Director del Archivo Histórico recibió a muchos investigadores de distintas disciplinas y, de entre ellas, también de Historia de la Contabilidad. Una de sus virtudes fue la de la acogida a los investigadores dándoles toda clase de explicaciones y ofreciendo su ayuda y orientación en base a sus años de investigador en este Archivo.

Ante su inesperado fallecimiento valga este pequeño homenaje póstumo. Por eso me he permitido pedirle a su buen amigo, Santiago Luxán, de la Universidad de las Palmas, que nos glosara su carrera académica.

En nombre de los historiadores de la contabilidad que nos hemos acercado al Archivo que dirigías: gracias José Manuel.

Thinking Critically in Space: Toward a Mixed-Methods Geospatial Approach to Education Policy Analysis
Authors: Yoon Ee-Seul , Lubienski Christopher
Published: October 2017

This paper suggests that synergies can be produced by using geospatial analyses as a bridge between traditional qualitative-quantitative distinctions in education research. While mapping tools have been effective for informing education policy studies, especially in terms of educational access and choice, they have also been underutilized and underdeveloped. This paper focuses on the potential benefits of expanding geospatial analysis, which has traditionally been heavily quantitative in its orientation, by incorporating qualitative research, including the accounts of lived experiences and perceptions that guide and shape institutional and individual behaviors and decisions. To that end, the paper proposes an agenda for mixed-methods research by drawing on new advances in the fields of human and critical geography.
Adoption of Open Access Publishing by Academic Researchers in Kenya
Authors: Chilimo Wanyenda , Adem Aggrey , Otieno Ajwang' Nicholas Walter , Maina Mary
Published: October 2017

This study investigates Kenyan scholars' adoption of open access (OA). The authors used a questionnaire to collect data from academic researchers at selected Kenyan public universities. The findings of this study indicate that while Kenyan researchers have embraced the concept of OA, challenges such as a lack of mechanisms to guide academic researchers on where to publish, a dearth of funding mechanisms to cover article processing charges, and a lack of accreditation mechanisms for regional and national journals are exposing Kenyan academic researchers to unscrupulous journal publishers and predatory publishing outlets. OA advocates in Kenyan universities need to devise innovative ways of raising awareness about OA, and these universities should provide the environment, infrastructure, and capacity building needed to support OA.
Early Laparoscopic Cholecystectomy in acute cholecystitis and its sequlae: Experience in tertiary care hospital
Authors: Ratan Md Ezharul Haque , Alam Hasina
Published: October 2017

Background: Acutecholecystitis (AC) is a common surgical condition requiring emergency hospitalization. Traditionally, these patients were treated conservatively, followed by delayed surgery six weeks or longer after acute event has subsided. Recently, early emergency cholecystectomy at same admission is suggested. This has the advantage of reduced length of stay (LOS) in hospital without any significant increase in complication rate. Moreover, conservative management is not always successful. We are here, observing the feasibility of emergency cholecystectomy in practical setting.Method: Between March 2008 and March 2017, 483 patients were admitted in a surgical unit of BIRDEM general hospital with the diagnosis of acute cholecystitis or its complications. The patients were assessed clinically with laboratory and imaging investigations. We planned early laparoscopic cholecystectomy (ELC) in all case, as soon as assessment and resuscitation were completed, irrespective of duration from symptom onset. Cases were analyzed for gender, age, operation time, volume of blood loss, conversion to open surgery, post-operative complication and length of hospital stay.Results: A total of 483 patients with AC and its sequlae were admitted, between March 2008 and March 2017 in a single unit of a tertiary care hospital which deals most of the diabetic patients of the country. Among them 477 patients were treated with emergency or urgent laparoscopic cholecystectomy (LC). The earlier the patient presented for surgery and those who were treated with antibiotics were easier to operate. Incidence of gangrene and perforation were more among those with acalculus cholecystitis. Surgical procedures were the most difficult in those presented beyond two weeks of symptom onset. Consequently operation time was over 100 minutes and blood loss was more than 250ml in such cases. Fortunately none required conversion to open procedure. Subhepatic drain were used in 17 cases. Subcutaneous simple tube drain in umbilical port was used in those with gangrene, perforation and transmural gall bladder wall pyogenic infection. Consequently umbilical port infection were very low (3cases, 0.6%). One patient presented with subhepatic fluid collection, 6 weeks after emergency LC. Laparotomy was done and found to have altered blood and pseudo-aneurysm of cystic artery (chronic blood loss from one of its lateral twig). Length of stay (LOS) in hospital were short (mean-1.8days, range: 20hours-4 days) except those with bile leak (5, 8 and 9 days respectively). None of the cases had bile duct injury or uncontrolled bleeding. There was no mortality in this series.Conclusion: Early laparoscopic cholecystectomy (ELC) has proved to be an effective and safe day case surgical procedure for AC and their complications. It provides much benefits with low complication and conversion in experienced hands.Bangladesh Crit Care J September 2017; 5(2): 101-105

Published: October 2017

Background: Major Depressive Disorder (MDD) is associated with reduced lung function.Objectives: To observe & compare FEF25%-75% in Major Depressive Disorder patients with control group.Methods: This prospective study was carried out in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU) from January to December, 2014 to assess the lung function status in newly diagnosed MDD patients. For this, 30 newly diagnosed female MDD patients (group B), aged 20 to 50 years were enrolled from the Department of Psychiatry of BSMMU. For control (group A) age, BMI, and occupation matched 30 apparently healthy females were randomly selected by personal contact. FEF25%-75% of all subjects were assessed by a portable digital spirometer (PONY FX, Cosmed, Italy). For statistical analysis, ANOVA, Independent samplet test were done and p value ?0.05 was considered as level of significance.Results: FEF25%-75%was significantly lower (p?0.001) in all MDD patients than control.Conclusion: From this study it may be concluded that the ventilatory lung function is significantly reduced in newly diagnosed MDD patients.Bangladesh Crit Care J September 2017; 5(2): 126-128

Lightning injuries are injuries caused by lightning strikes. Lightning delivers a massive electrical pulse over a fraction of a millisecond. It can kill a person by instantaneously short-circuiting the heart. Lightning injuries have been the second most common cause of storm-related death in the United States1,2,3. Far more injuries and deaths occur in tropical and subtropical countries. Here we present the case report of a 45 year old Bangladeshi lady who was struck by lightning. Patient presented with immediate loss of consciousness and some superficial skin burn about 1 hour following the event. Over the next few days she was found to have intracerebral haemorrhage and infarct, tympanic membrane rupture and bilateral cataract. Surprisingly patient did not suffer from any cardiac or renal injury. All lightning strike victims should receive emergency medical support on site of injury and be treated in intensive care units (ICU) equipped with multiple organ support facility.Bangladesh Crit Care J September 2017; 5(2): 132-134

Published: October 2017

Background: Ticagrelor, a reversible P2Y12 receptor inhibitor may represent a significant advancement over currently available oral antiplatelet drugs in treatment of ischaemic heart disease.The study was intended to compare the effect of Ticagrelor and Clopidogrel on oxidative stress markers in patients of chronic stable angina (CSA) following percutaneous coronary intervention (PCI).Methods: The study included a total of 100 CSA patients. Patients were divided into two groups, Ticagrelor and Clopidogrel treated groups (each having 50 patients). The baseline laboratory parameters-Malondihyde (MDA), Reduced glutathione (GSH), bleeding time, clotting time and platelet count, were measured and then patients of both groups underwent PCI. The same parameters were again assessed at follow up after 4 weeks of intervention. Comparisons of the laboratory parameters were made between two groups at baseline and at follow up and also within group before and after intervention.Results: The level of plasma MDA in Ticagrelor group was significantly reduced from baseline to follow up(4.5 ± 1.8 to 1.4 ± 0.7, p <0.001) and in Clopidogrel group (4.2 ± 1.2 to 1.3 ± 0.7, p <0.001). GSH level was increased from 0.7 mg/dl to 2.5 mg/dl (p <0.001) in Ticagrelor group and in Clopidogrel group 0.6 mg/dl to 1.4 mg/dl, p <0.001).Conclusion: The study concluded that both Ticagrelor and Clopidogrel have similar effect on oxidative stress markers, resulting from oxidative injury processes in patients of chronic stable angina.Cardiovasc. j. 2017; 10(1): 40-44

Authors: Hoque Asraful , Uddin Mauin , Moinuddin Shahriar
Published: October 2017

Background: This study was designed to assess the role of topically applied tranexamic acid in pericardial cavity in reducing post operative bleeding.Methods: This study is a non-randomized, double blinded, clinical trial, conducted in the Department of Cardiac Surgery, National Institute of Cardiovascular Diseases from January 2014 to December 2015 among the patients admitted for off pump coronary artery bypass (OPCAB) surgery. A total of 60 patients were recruited for the study and they were divided in two groups- 30 patients in tranexamic acid group (Group I) and 30 patients in placebo group (Group II). On completion of the grafting, before closure of the sternum tranexamic acid (2.5 g/25 ml) or placebo (25 ml of saline) diluted in 100 ml of warm saline (37 °C) was instilled into the pericardial cavity including the mediastinal tissues and left for 5 minutes. Total mediastinal bleeding and packed red cell transfusion were estimated in the postoperative period in both groups.Results: There was no significant difference noted in baseline demographic data, basic clinical characteristics and preoperative coagulation profile between the 2 groups (P > 0.05). Total mediastinal bleeding and packed red cell transfusion in group I and group II patients was 421.67±70.32vs 593.33±77.38ml, p<0.001 and 0.87±0.0.73 units vs1.77±0.57 units, p<0.001.No patient required reoperation for bleeding and there was no incidence of myocardial infarction (MI), thrombo-embolism, deep venous thrombosis (DVT) or stroke in none of the patients in either group.Conclusion: Topical application of tranexamic acid can significantly and safely reduce postoperative mediastinal bleeding. It also reduces whole blood transfusion requirements during immediate postoperative period among patients undergoing OPCAB surgery.Cardiovasc. j. 2017; 10(1): 52-55

Published: October 2017

Background: Prophylactic efficiencies of teicoplanin and meropenem against infections in open heart surgery were investigated in a retrospective observational study.Method: In new regime of antibiotics single dose of teicoplanin and 72 hours coverage with meropenem were used in open heart surgery. One dose of teicoplanin was administered during induction of general anesthesia. First dose of meropenem was administered during induction of general anesthesia, and then 8 to 12 hourly continued up to 72 hours. This regime of antibiotics was compared retrospectively with previous regime of antibiotics containing flucloxacillin, ceftriaxone and gentamycin continuing from induction of general anesthesia up to 5th post operative day.Results: In 203 patients receiving new regime containing teicoplanin and meropenem, there was no infection and there was no nephrotoxicity. But in 101 patients receiving conventional regime containing flucloxacillin cefriaxone and gentamycin, there were 21 patients (21%) with surgical site infections; among them 3 patients expired, and nephrotoxicity developed in 15(14.85%) patients.Conclusion: As prophylactic agent combination of teicoplanin and meropenem may be more effective and safer against infection in open heart surgery.Cardiovasc. j. 2017; 10(1): 63-67
Coronary Endarterectomy with off Pump Coronary Artery Bypass Surgery- A Review
Authors: Ranjan Redoy , Adhikary Dipannita , Saha Heemel , Saha Sanjoy Kumar , Mandal Sabita , Adhikary Asit Baran
Published: October 2017

Coronary endarterectomy is first described as an alternative surgical procedure for myocardial revascularization against diffuse coronary artery disease by Baily et al. in 1956. Coronary endarterectomy provides complete surgical revascularization of the myocardium in diffuse and calcified coronary arteries with adequate blood flow to distal part of occluded arteries, thus improving ventricular function. However, the initial outcomes of coronary endarterectomy were not satisfactory but now-a-days different studies have shown that coronary endarterectomy with coronary artery bypass grafting can be done safely with acceptable morbidity and mortality. Moreover, the graft patency rate on angiographic evaluation is also good following coronary endarterectomy. So, its time to reevaluate this old techniques, and reanalysis the current outcomes of coronary endarterectomy and readdress its indication in diffuse coronary artery diseaseCardiovasc. j. 2017; 10(1): 84-90

Lingual and Sublingual Haematoma in a Patient Following Streptokinase Administration in Acute Myocardial Infarction- A Case Report
Authors: Alam Shoaeb Imtiaz , Md Jamil Abu Bakar , Parvin Tanjima , Mahbub SM Ear E , Siddique Md Abu
Published: October 2017

The value of thrombolysis by Streptokinase administration in the treatment of acute myocardial infarction is well established. Haemorrhage is a common complication of fibrinolytic therapy. Here, we report an unusual case of spontaneous lingual and sublingual haematoma following streptokinase therapy after acute myocardial infarction. A 57-year-old man with a diagnosis of acute ST elevated myocardial infarction treated with streptokinase developed a large lingual and sublingual haematoma. Though his airway was not compromised, he had difficulty in swallowing. A conservative approach was made by starting parenteral nutrition, preventing rethrombosis by not reversing the action of streptokinase as his coagulation profile was within normal limits and maintaining optimum blood pressure, blood glucose level and urine output. His tongue swelling subsided after four days and oral medication and feeding was started. No complication occurred during this period. Though there is no adequate information regarding the management of the patient, a vigilant monitoring of the patency of the airway with a conservative approach by not reversing the effect of streptokinase and preventing coronary rethrombosis may produce a better outcome in such cases.Cardiovasc. j. 2017; 10(1): 97-100

Systemic lupus erythematosus (SLE) is a multiorgan autoimmune disease in which skin is involved in up to 85% of cases. Lower extremity ulcers are an infrequent but disabling complication of SLE. Critical peripheral ischemia (CPI) is also an uncommon but potentially devastating feature of SLE. We reported a case o f SLE who presented with multiple ulcers along with digital infarcts of upper and lower limbs. She had features of digital bone infarct of left hand and right foot. She also had features of pulmonary interstitial involvement with pulmonary hypertension. All of these features were found within three months of disease onset which is very rare. She was treated with intravenous Methylprednisolone followed by oral Prednisolone, Hydroxychloroquinine, Azathioprine, Diuretic, Bosentan, Aspirin and Nifedipine in combinaton. Later warfarin was added after one month. She showed significant improvement after three months of treatment.J Bangladesh Coll Phys Surg 2017; 35(3): 150-154

De Quervains Thyroiditis (sub-acute thyroiditis)
Authors: Nabi G , Rahman NMW , Azad MAK , Hassan M , Bonik M
Published: October 2017

Inflammatory diseases of the thyroid can be classified into three broad categories: acute, subacute and chronic thyroiditis. Subacute disease includes granulomatous or De Quervains thyroiditis and lymphocytic thyroiditis or silent thyroiditis. The gland swells up and is very painful and tender. As thyroid hormones are discharged into the blood, patient becomes hyperthyroid clinically but the gland cannot take up iodine so the radioactive iodine uptake is very low. The hyperthyroidism generally resolves after a few weeks. The relief of pain by giving NSAID or steroids in this condition is so dramatic as to be almost diagnostic. A 40 year old man, hailing from Nawabganj, Dhaka was diagnosed as De Quervains thyroiditis and treated successfully. In this report, the case condition, procedures of diagnosis and treatment are reported in details.Mediscope Vol. 4, No. 1: Jan 2017, Page 35-37
Reducing Severity of Late Blight (Phytophthora infestans) and Improving Potato (Solanum tuberosum L.) Tuber Yield with Pre-Harvest Application of Calcium Nutrients
Authors: Seifu Yewubnesh Wendimu
Published: October 2017

The efficiency of pre-harvest application of calcium chloride alone, calcium nitrate alone, and combined application of calcium chloride and calcium nitrate (1:1) was evaluated in reducing the severity of P. infestans and improving potato tuber yield. Pot experiment was conducted in randomized complete block design with four replications. The treatments consisted of combination of two potato varieties (Shenkola and Gera) and three types of calcium nutrients (calcium chloride alone, calcium nitrate alone, and calcium chloride mixed with calcium nitrate), each at three levels (5, 10, and 15 g per liter per plant) and the control treatment (0 g of calcium nutrients). In comparison to the control treatment, the application of calcium nutrients significantly decreased the severity of late blight disease and improved potato tuber yield. The effect of calcium nutrients on the severity of late blight disease and potato tuber yield differed among the two potato varieties. The maximum severity reduction (60%) was noticed in the Gera potato variety with the application of calcium chloride mixed with calcium nitrate (1:1), supplied at 15 g per plant. However, the highest average tuber yield was obtained with the application of calcium nitrate at 15 g per plant, and average tuber yield was increased by 77% in both potato varieties. Hence, foliar application of either calcium nitrate alone or calcium nitrate mixed with calcium chloride was found to be more efficient than the application of calcium chloride alone. This result suggests that the nitrate ion present in the calcium nitrate may make a difference in terms of reducing the severity of late blight disease and improving potato tuber yield. The lowered severity of late blight disease and the increased tuber yield in potato plants sprayed with calcium nutrients may be because of the higher accumulation of calcium in the plant tissue.
Photo Protection of Haematococcus pluvialis Algae by Astaxanthin: Unique Properties of Astaxanthin Deduced by EPR, Optical and Electrochemical Studies
Authors: Focsan A. , Polyakov Nikolay , Kispert Lowell
Published: October 2017

Abstract The antioxidant astaxanthin is known to accumulate in Haematococcus pluvialis algae under unfavorable environmental conditions for normal cell growth. The accumulated astaxanthin functions as a protective agent against oxidative stress damage, and tolerance to excessive reactive oxygen species (ROS) is greater in astaxanthin-rich cells. The detailed mechanisms of protection have remained elusive, however, our Electron Paramagnetic Resonance (EPR), optical and electrochemical studies on carotenoids suggest that astaxanthin’s efficiency as a protective agent could be related to its ability to form chelate complexes with metals and to be esterified, its inability to aggregate in the ester form, its high oxidation potential and the ability to form proton loss neutral radicals under high illumination in the presence of metal ions. The neutral radical species formed by deprotonation of the radical cations can be very effective quenchers of the excited states of chlorophyll under high irradiation.

Published: October 2017

The digital time delay integration (digital TDI) technology of the complementary metal-oxide-semiconductor (CMOS) image sensor has been widely adopted and developed in the optical remote sensing field. However, the details of targets that have low illumination or low contrast in scenarios of high contrast are often drowned out because of the superposition of multi-stage images in digital domain multiplies the read noise and the dark noise, thus limiting the imaging dynamic range. Through an in-depth analysis of the information transfer model of digital TDI, this paper attempts to explore effective ways to overcome this issue. Based on the evaluation and analysis of multi-stage images, the entropy-maximized adaptive histogram equalization (EMAHE) algorithm is proposed to improve the ability of images to express the details of dark or low-contrast targets. Furthermore, in this paper, an image fusion method is utilized based on gradient pyramid decomposition and entropy weighting of different TDI stage images, which can improve the detection ability of the digital TDI CMOS for complex scenes with high contrast, and obtain images that are suitable for recognition by the human eye. The experimental results show that the proposed methods can effectively improve the high-dynamic-range imaging (HDRI) capability of the digital TDI CMOS. The obtained images have greater entropy and average gradients.

Published: October 2017

The spectroscopic method for gas temperature determination in argon non-thermal plasmas sustained at atmospheric pressure proposed recently by Spectrochimica Acta Part B 129 14 (2017)—based on collisional broadening measurements of selected pairs of argon atomic lines, has been applied to other pairs of argon atomic lines, and the discrepancies found in some of these results have been analyzed. For validation purposes, the values of the gas temperature obtained using the different pairs of lines have been compared with the rotational temperatures derived from the OH ro-vibrational bands, using the Boltzmann-plot technique.
Assessing the Relationship between Measurement Length and Accuracy within Steady State Co-Heating Tests
Authors: Stamp Samuel , Altamirano-Medina Hector , Lowe Robert
Published: October 2017

Evidence of a fabric performance gap has underlined the need for measurements of in situ building performance. Steady state co-heating tests have been used since the 1980s to measure whole building heat transfer coefficients, but are often cited as impractical due to their 2–4 week test duration and limited testing season. Despite this, the required conditions for testing and test duration have never been fully assessed. Analysis of field tests show that in 12 of 16 cases, a heat loss estimate to within 10% of the result achieved across a full test period can be achieved within just 72 h. These results are supported by simulated tests upon a wider range of dwellings and across wider environmental conditions. However, systematic errors may still exist, even in cases of convergence and cases with significant uncertainties may never converge. Simulated examples of traditional dwellings and those built in line with current building regulation limits may be tested for more than half the year. However, even when simulated with reduced uncertainties, dwellings with low heat loss and high solar gains, such Passivhaus dwellings and apartments, could be successfully tested for just 22% and 12% of a year respectively, demonstrating the limitations of the co-heating method in assessing such dwellings.

Authors: Salca Emilia-Adela , Krystofiak Tomasz , Lis Barbara
Published: October 2017

The objective of this study was to optimize the sanding and coating processes of black alder wood to promote and support its use in furniture manufacturing. Two criteria have been applied for process optimization, namely, the minimum surface roughness of the samples and power consumption during sanding as a function of various sanding systems. The surface roughness of the sanded specimens and the power consumption during sanding strongly depends on the grit size used. Two eco-varnishes were applied to the samples by spraying. Moreover, the effect of the surface preparation and varnish type on the coating properties expressed by the varnish layer adherence to the substrate and surface glossiness was evaluated. For better glossiness values, the UV-cured varnish was preferred. The sanding with a grit sequence of 60, 120, and 150 grit size abrasives was found to be optimal when applied to black alder wood, and it is recommended to obtain performant UV-coated wood surfaces for furniture products.
The #BTW17 Twitter Dataset–Recorded Tweets of the Federal Election Campaigns of 2017 for the 19th German Bundestag
Authors: Kratzke Nane
Published: October 2017

The German Bundestag elections are the most important elections in Germany. This dataset comprises Twitter interactions related to German politicians of the most important political parties over several months in the (pre-)phase of the German federal election campaigns in 2017. The Twitter accounts of more than 360 politicians were followed for four months. The collected data comprise a sample of approximately 10 GB of Twitter raw data, and they cover more than 120,000 active Twitter users and more than 1,200,000 recorded tweets. Even without sophisticated data analysis techniques, it was possible to deduce a likely political party proximity for more than half of these accounts simply by looking at the re-tweet behavior. This might be of interest for innovative data-driven party campaign strategists in the future. Furthermore, it is observable, that, in Germany, supporters and politicians of populist parties make use of Twitter much more intensively and aggressively than supporters of other parties. Furthermore, established left-wing parties seem to be more active on Twitter than established conservative parties. The dataset can be used to study how political parties, their followers and supporters make use of social media channels in political election campaigns and what kind of content is shared.
Performance Improvement of Plug-and-Play Dual-Phase-Modulated Quantum Key Distribution by Using a Noiseless Amplifier
Authors: Bai Dongyun , Huang Peng , Ma Hongxin , Wang Tao , Zeng Guihua
Published: October 2017

We show that the successful use of a noiseless linear amplifier (NLA) can help increase the maximum transmission distance and tolerate more excess noise of the plug-and-play dual-phase-modulated continuous-variable quantum key distribution. In particular, an equivalent entanglement-based scheme model is proposed to analyze the security, and the secure bound is derived with the presence of a Gaussian noisy and lossy channel. The analysis shows that the performance of the NLA-based protocol can be further improved by adjusting the effective parameters.
Construction of New Fractional Repetition Codes from Relative Difference Sets with λ=1
Authors: Kim Young-Sik , Park Hosung , No Jong-Seon
Published: October 2017

Fractional repetition (FR) codes are a class of distributed storage codes that replicate and distribute information data over several nodes for easy repair, as well as efficient reconstruction. In this paper, we propose three new constructions of FR codes based on relative difference sets (RDSs) with λ = 1 . Specifically, we propose new ( q 2 - 1 , q , q ) FR codes using cyclic RDS with parameters ( q + 1 , q - 1 , q , 1 ) constructed from q-ary m-sequences of period q 2 - 1 for a prime power q, ( p 2 , p , p ) FR codes using non-cyclic RDS with parameters ( p , p , p , 1 ) for an odd prime p or p = 4 and ( 4 l , 2 l , 2 l ) FR codes using non-cyclic RDS with parameters ( 2 l , 2 l , 2 l , 1 ) constructed from the Galois ring for a positive integer l. They are differentiated from the existing FR codes with respect to the constructable code parameters. It turns out that the proposed FR codes are (near) optimal for some parameters in terms of the FR capacity bound. Especially, ( 8 , 3 , 3 ) and ( 9 , 3 , 3 ) FR codes are optimal, that is, they meet the FR capacity bound for all k. To support various code parameters, we modify the proposed ( q 2 - 1 , q , q ) FR codes using decimation by a factor of the code length q 2 - 1 , which also gives us new good FR codes.
Prior Elicitation, Assessment and Inference with a Dirichlet Prior
Authors: Evans Michael , Guttman Irwin , Li Peiying
Published: October 2017

Methods are developed for eliciting a Dirichlet prior based upon stating bounds on the individual probabilities that hold with high prior probability. This approach to selecting a prior is applied to a contingency table problem where it is demonstrated how to assess the prior with respect to the bias it induces as well as how to check for prior-data conflict. It is shown that the assessment of a hypothesis via relative belief can easily take into account what it means for the falsity of the hypothesis to correspond to a difference of practical importance and provide evidence in favor of a hypothesis.
Newton Power Flow Methods for Unbalanced Three-Phase Distribution Networks
Authors: Sereeter Baljinnyam , Vuik Kees , Witteveen Cees
Published: October 2017

Two mismatch functions (power or current) and three coordinates (polar, Cartesian and complex form) result in six versions of the Newton–Raphson method for the solution of power flow problems. In this paper, five new versions of the Newton power flow method developed for single-phase problems in our previous paper are extended to three-phase power flow problems. Mathematical models of the load, load connection, transformer, and distributed generation (DG) are presented. A three-phase power flow formulation is described for both power and current mismatch functions. Extended versions of the Newton power flow method are compared with the backward-forward sweep-based algorithm. Furthermore, the convergence behavior for different loading conditions, R / X ratios, and load models, is investigated by numerical experiments on balanced and unbalanced distribution networks. On the basis of these experiments, we conclude that two versions using the current mismatch function in polar and Cartesian coordinates perform the best for both balanced and unbalanced distribution networks.
Dynamic Modeling and Simulation of Deep Geothermal Electric Submersible Pumping Systems
Authors: Kullick Julian , Hackl Christoph
Published: October 2017

Deep geothermal energy systems employ electric submersible pumps (ESPs) in order to lift geothermal fluid from the production well to the surface. However, rough downhole conditions and high flow rates impose heavy strain on the components, leading to frequent failures of the pump system. As downhole sensor data is limited and often unrealible, a detailed and dynamical model system will serve as basis for deeper understanding and analysis of the overall system behavior. Furthermore, it allows to design model-based condition monitoring and fault detection systems, and to improve controls leading to a more robust and efficient operation. In this paper, a detailed state-space model of the complete ESP system is derived, covering the electrical, mechanical and hydraulic subsystems. Based on the derived model, the start-up phase of an exemplary yet realistic ESP system in the Megawatt range—located at a setting depth of 950 m and producing geothermal fluid of 140 ∘ C temperature at a rate of 0.145 m 3 s − 1 —is simulated in MATLAB/Simulink. The simulation results show that the system reaches a stable operating point with realistic values. Furthermore, the effect of self-excitation between the filter capacitor and the motor inductor can clearly be observed. A full set of parameters is provided, allowing for direct model implementation and reproduction of the presented results.
