Authors: Bula Romero Javier , Guzmán Arteaga María del Pilar , Sánchez Caraballo Álvaro 
Published: November 2019

Objective. To describe the demographic characteristics and interventions performed as well as the maternal out comes in women who presented hemorrhage in the first 24 hours postpartum or post-cesarean in a medium-complexity hospitalin Monteria,Colombia, South America. Materials and method. This was a retrospective, descriptive, and exploratory study based on the analysis of clinical records. Results. The patients’ ages ranged between 13 and 42 years. The major it y were multiparous; more than 50% of the patients lived in a consensual union and resided in the urban area. 75% of the cases identified were sent from the first level sof health care in the department of Córdoba. The issue retention and traumatisms in the vaginal canal were the central causes of postpartum hemorrhage. 50%of the cases required blood transfusion with red blood cells or Rh. 17% required admission to an ICU and 33% of the remaining cases required surgical management. Two patients required subtotal hysterectomy, and both were first-regnancy adolescents. Conclusions. The most frequent causes of postpartum hemorrhage in vaginal deliveries are related to traumatisms in the vaginal canal and to the retention of placental tissue and remains of ovular membranes.

Published: November 2019

Objective. To explore the life history of an adolescent who experiences cancer. Materials and methods. This is a qualitative study based on single-case life history. In-depth interview was used, and the results were analyzed using a reduced version of Amedeo Giorgi’s method. Results. Two central themes emerged from the data: Diagnosis implications for the personal, social and, family life of a teenager suffering from cancer and family support as crucial in coping with the disease. The support of the family was essential in overcoming cancer in an adolescent. Solid social support to the patient favored the processes of living, adapting, coping with and, overcoming cancer. Conclusions. The study allowed the researchers to understand an adolescent’s experience of living with osteosarcoma, revealing a particular world that has not been explored in depth. Sometimes childhood cancer is considered a devastating disease, which has severe implications for the patient and his family forcing them to reorganize their family and social dynamics to adapt and fight against that disease.

Published: November 2019

Aim:
To estimate direct and indirect costs of surgical treatment of abnormal uterine bleeding (AUB) from a self-insured employer's perspective.
Methods:
Employer-sponsored insurance claims data were analyzed to estimate costs owing to absence and short-term disability 1 year following global endometrial ablation (GEA), outpatient hysterectomy (OPH) and inpatient hysterectomy (IPH).
Results:
Costs for women who had GEA are substantially less than costs for women who had either OPH or IPH, with the difference ranging from approximately $7700 to approximately $10,000 for direct costs and approximately $4200 to approximately $4600 for indirect costs. Women who had GEA missed 21.8–24.0 fewer works days.
Conclusion:
Study results suggest lower healthcare costs associated with GEA versus OPH or IPH from a self-insured employer perspective.

Published: November 2019

This paper identifles and determines the main parameters used to calculate the dlscharge coefficlent of a toroidal Venturl nozzle accordlng to the ISO Standard 9300, operating at the critical flow regime (sonlc). Thls study was conducted to investigate the effeds of the viscous stresses In the turbulent boundary layer, the wall thermal boundary condition, and the flow fleld curvature at the nucleus of the nozzle on the dlscharge coefflclent by means of a theoretical and numerlcal approach. Characterlzation of the dlscharge coefflclent in the Venturi sonlc nozzle was performed consldering the viscous and multidlmenslonal effects of the flujd flow as uncoupled phenomenon. As a result. each non-ideal mechanism can be analyzed independently from the Inftuence of the other mechanlsm. We present a numerlcal procedure to characterlze the dlscharge coefflclent In the invlscld reglon of the ftow, by uslng the numerical simulation of the inviscld maln ftow by means of the commerclal CFD code. In the region of the vlscous stresses, the charaderlzation of thls coefflclent is based on the analytlcal theory of the turbulent boundary layer. Thls charaderization allowed obtalning a correlation of the dlscharge coefflclent that was valldated by dlred comparlson between the experimental correlations of the dlscharge coefflclent In turbulent boundary layer proposed by ISO-9300 and the Korea Research Institute of Standards and Sclence (KRISS). Thls valldation was carried out for throat Reynolds numbers from 1.4 to 2.6x10'. The agreement of the theoretical and measured dlscharge coefflclents by these correlations was better than 0.2%.
Review of Relevant System Development Life Cycles (SDLCs) in Service-Oriented Software Engineering (SoSE)
Authors: Rodríguez-Martínez L. , Mora M. , Álvarez F. , Garza L. , Durán H. , Muñoz J. 
Published: November 2019

Service-oriented software engineering (SoSE) is a new paradigm for building software systems, fostered by the availability of a new -but already mature- computing technology based on services. SoSE advances the current object-oriented and the component-based software engineering paradigms. Under that new paradigm, multiple software-system development life cycle (SDLC) methodologies have been proposed; however, none of them have gained a total acceptance as the dominant SDLC in SoSE. On this theoretical and practical situation, we believe that a research is required to reach more standardized and stabilized knowledge about SDLCs in SoSE. Thus, this article reviews nine recent SDLCs proposed for SoSE with the aim to present a descriptive-comparative landscape of a relevant range of SDLCs for SoSE. Such description-comparison is guided by two criteria: (i) the extent of completeness of each SDLC, with respect to the proposed phases, activities and delivered artifacts, and (ii) the extent of the Boehm-Turner’s Rigor-Agility balance. Our results suggest that only three of the nine SDLCs studied already provide the best level of completeness and Rigor-Agility. Finally, we consider that the reported descriptivecomparative framework and their findings from each SDLC can be useful also for comparing and elaborating future SDLCs in SoSE.

Published: November 2019

Hybrid MIMO space-time codes combine the benefits of spatial multiplexing with diversity gain to achieve both high spectral efficiency and link reliability. In this paper, we present a family of hybrid codes, known as LD STBC-VBLASTcodes, along with a receiver architecture suitable for low-complexity hardware implementation. We show that, under Rayleigh fading, the performance of LD STBC-VBLAST codes is superior to other recently proposed hybrid codes. We also present a technique to derive, from a given propagation scenario, spatially correlated MIMO channel models adequate for space-time coding performance analysis. Using this technique, we evaluate the performance of LD STBC-VBLAST codes under several correlated channels

Published: November 2019

The accuracy on time delay estimation given pairs of irregularly sampled time series is of great relevance in astrophysics. However the computational time is also important because the study of large data sets is needed. Besides introducing a new approach for time delay estimation, this paper presents a parallel approach to obtain a fast algorithm for time delay estimation. The neural network architecture that we use is general Regression Neural Network (GRNN). For the parallel approach, we use Message Passing Interface (MPI) on a beowulf-type cluster and on a Cray supercomputer and we also use the Compute Unified Device Architecture (CUDA™) language on Graphics Processing Units (GPUs). We demonstrate that, with our approach, fast algorithms can be obtained for time delay estimation on large data sets with the same accuracy as state-of-the-art methods.

Published: November 2019

In this article a hardware topology meant to compare the velocity performance of both an induction motor and a permanent magnet (PM) AC three-phase motor is presented. A variable reference is tracked by the sensorless vectorcontrolled adjustable speed drive (ASD) that permits, by means of the same type of control, performing the speed control loop of the two motors. The algorithms are programmed on a digital signal processor (DSP) in order to ensure efficient use of energy in the transistor bridge and proper tracking of the reference at low and high speeds. Regarding the torque performance, a laboratory test bed based on a torquemeter and two motors is constructed. The hardware implementation includes the power and the digital stages. A serial communication between the PC and the ASD is accomplished to put into operation in the user front-end because a high speed sample frequency is required for the analysis software that runs in the PC. This interface is used not only as comparing the speed response of the motors signals but also as looking the power quality analysis of each motor measurements based on software. Results are presented to demonstrate the effectiveness of the sensorless scheme.

Published: November 2019

This work presents a performance evaluation of two of the most popular end-to-end third generation technologies. The technologies analyzed were EVDO Rev. A and HSDPA. Although these technologies are present around the world, most of the work based on these technologies is only simulation, being most of the real-case scenario investigations, internal carrier studies. We used a real-case scenario using TCP and UDP. We measured throughput, jitter and packet loss/discard as QoS performance parameters. We performed tests using both technologies concurrently with two identical computers at downlink and uplink at 0 km/h, 60 km/h and 90 km/h. These computers send/receive data to a static server host located in California. In general, we noticed that HSDPA and EVDO lose performance when speed increases. The most affected performance parameter was the throughput being most of the average values under 50 percent of the nominal throughput value. At downlink, HSDPA was the most speed increase sensitive technology and at uplink EVDO was the most speed sensitive. HSDPA at downlink goes from 32.9 percent of the nominal throughput value to 8.57 percent of nominal throughput value at 90 km/h. EVDO in the uplink goes from 17.11 percent of nominal throughput value to 6.79 percent of the nominal throughput value at 90 km/h.
