This paper describes an improved building treatment approach (IBTA) for use in urban inundation modeling. In this approach, the ground surface elevation was raised by the threshold (h) of the building entrance height to account for both the blockage and storage effect of areas with dense building coverage. A higher roughness coefficient was assigned to the areas where buildings were located to compensate for the resistance effects caused by the inner wall of the structure. The campus of Huazhong University of Science and Technology (HUST) in Wuhan City, China, was used as a case study. Comparison between IBTA and several traditional building treatment approaches suggested that the model results were sensitive to the building treatment method and the threshold used for terrain preprocessing in dense building regions. Furthermore, as the interaction between the surface water flow and dense buildings were adequately represented by using a new terrain preprocessing approach, the proposed IBTA provided better performance in terms of maximum inundation depth and the peak depth time than the traditional approaches in areas with dense building coverage, such as that of the campus.

Multimorbid Patients

Patients with chronic wounds (leg ulcers, decubitus, and diabetic foot ulcers) suffer from marked restrictions in their quality of life and can often no longer adequately carry out their everyday tasks. The need for nursing and medical care increases when other illnesses and complaints are present at the same time. Qualified wound care and the treatment of comorbidities are therefore of particular importance. The treatment of this disease, which is increasing in number, requires a holistic, multimodal treatment approach which, in addition to professional wound care, also includes comorbidities in the treatment. This case study describes an old treatment method for refractory wounds, the so-called “maggot therapy”, and shows how this is integrated into a holistic, multimodal therapeutic approach.

The migration of Zimbabweans into South Africa is shaped by several factors and processes. Traditionally, the decision to migrate was mostly based on family considerations (where gender stereotypic roles were a priority), although in some cases the migrants exercised individualism and personal agency. This led to migration trends that were male dominated. Current Zimbabwean migration trends reflect large volumes of women as the socio-economic crisis forces them to leave their country. These migrant women encounter a myriad of challenges in their host countries. This paper explores Zimbabwean women’s migration to the town of Mthatha in South Africa, highlighting their challenges and the strategies they employ to overcome these, as found in a recent case study. Applying a qualitative research design and using questionnaires and interviews to gather data from the 100 purposively sampled women, the study found that many Zimbabwean migrant women in Mthatha encountered numerous challenges. They lacked the required documents to live and work in South Africa, experienced exploitation and marriage constraints, and had broken ties with their families back in Zimbabwe. According to the study, these women managed to navigate these challenges, rising above the stereotypic norms and values that used to label them as non-productive citizens to superheroes who were supporting their families and the country’s economy—thus breaking the shackles of gender stereotyping to create new norms. These findings underline the importance of shifting from the traditional approaches to women migration and pursuing perspectives that present migration as a critical component of the process of social change and development to all migrants.

Segmental Testicular Infarction

The prevalence of segmental testicular infarction is extremely uncommon and very few cases have been reported in literature. Clinical and sonographic presentation of this condition can mimic testicular neoplasms or testicular torsion. Therefore, accurate diagnosis of segmental testicular infarction is imperative in the treatment process. This case study presents the sonographic diagnosis of testicular infarction in a 49-year-old man who reported mild testicular tenderness. A conservative treatment approach was used, saving the patient unnecessary surgical intervention.

We demonstrate the application of seismic methods using in-mine infrastructure such as exploration tunnels to image platinum deposits and geologic structures using different acquisition configurations. In 2020, seismic experiments were conducted underground at the Maseve platinum mine in the Bushveld Complex of South Africa. These seismic experiments were part of the Advanced Orebody Knowledge project titled “Developing technologies that will be used to obtain information ahead of the mine face.” In these experiments, we recorded active and passive seismic data using surface nodal arrays and an in-mine seismic land streamer. We focus on analyzing only the in-mine active seismic portion of the survey. The tunnel seismic survey consisted of seven 2D profiles in exploration tunnels, located approximately 550 m below ground surface and a few meters above known platinum deposits. A careful data-processing approach was adopted to enhance high-quality reflections and suppress infrastructure-generated noise. Despite challenges presented by the in-mine noisy environment, we successfully imaged the platinum deposits with the aid of borehole data and geologic models. The results open opportunities to adapt surface-based geophysical instruments to address challenging in-mine environments for mineral exploration.

AbstractThe conventional data envelopment analysis (DEA) measures the relative efficiency of decision making units (DMUs) consuming multiple inputs to produce multiple outputs under the assumption that all the data are exact. In the real world, however, it is possible to obtain interval data rather than exact data because of various limitations, such as statistical errors and incomplete information, et al. To overcome those limitations, researchers have proposed kinds of approaches dealing with interval DEA, which either use traditional DEA models by transforming interval data into exact data or get an efficiency interval by using the bound of interval data. In contrast to the traditional approaches above, the paper deals with interval DEA by combining traditional DEA models with error propagation and entropy, uses idea of the modified cross efficiency to get the ultimate cross efficiency of DMUs in the form of error distribution and ranks DMUs using the calculated ultimate cross efficiency by directional distance index. At last we illustrate the feasibility and effectiveness of the proposed method by applying it to measure energy efficiency of regions in China considering environmental factors.

AbstractThis paper presents a case study of model predictive control (MPC) applied to a continuous stirred tank reactor (CSTR). It is proposed to approximate nonlinear behavior of a plant by several local linear models, enabling a piecewise affine (PWA) description of the model used to predict and optimize future evolution of the reactor behavior. Main advantage of the PWA model over traditional approaches based on single linearization is a significant increase of model accuracy which leads to a better control quality. It is also illustrated that, by adopting the PWA modeling framework, MPC strategy can be implemented using significantly less computational power compared to nonlinear MPC setups.

Case Study Data

This case study considers the phonological forms of early lexical items produced by 1 normally developing boy, from 19 to 22 months of age, who began to produce all monosyllabic words as bisyllabic. In order to link this empirical data (the apparent creation of increased complexity) with universal tendencies (motivated by the reduction of complexity), the functions of reduplication were revisited. Phonological processes (i.e., reduplication and final consonant deletion) are viewed as repairs motivated by 2 interacting constraints (i.e., constraints on monosyllabic words and on word-final consonants). These longitudinal case study data provide further evidence for a relationship between final consonant deletion and reduplication. A possible treatment approach for similar patterns demonstrated clinically is recommended.

The Impact

The emerging of digital technology not only encourages the development of new tools but also changes traditional approaches to solving emerging problems. The sound, music, art, colors, etc. that prevailed in the 20th-century forms of therapy are being replaced by integrated systems that overcome many of these forms, thanks to digital technology. With the increasing number of people with autism spectrum disorder (ASD) in the world, such systems provide new opportunities for the treatment of these disorders. In this research, the creation of such a system has been chosen as the object of work. The article presents an interactive tool for the education of children with ASD created by audio, video, and computer technologies and assesses its potential impact. The experimental research and its results are presented. This study aims to evaluate an interactive instrument developed for the education of such children. Following the objectives of ensuring the interactivity of the process, provoking all the perceptions of the subject, and developing the subject's ability to respond to the environment, a personalized audiovisual environment was created. For interactivity, the virtual program EyeCon, Webcam and camcorders, video projector, and speaker system were used. The study was conducted with one subject and a case study method was used. The impact of the instrument was established based on a survey of the parents of the child and the findings of childcare experts. The results of the study demonstrated the positive benefits for this child such as increased eye-to-hand coordination, concentration duration, improved communication, and emotional expression. The results obtained show that such interactive multi-sensory environments in special and general education schools can be a supplemental tool for traditional methods.

Abstract. A synthetic aperture radar (SAR) data processing uses the backscattered electromagnetic wave to map radar reflectivity of the ground surface. The polarization property in radar remote sensing was used successfully in many applications, especially in target decomposition. This paper presents a case study to the experiments which are performed on ESAR L-Band full polarized data sets from German Aerospace Center (DLR) to demonstrate the potential of coherent target decomposition and the possibility of using the weather radar measurement parameter, such as the differential reflectivity and the linear depolarization ratio to obtain the quantitative information of the ground surface. The raw data of ESAR has been processed by the SAR simulator developed using MATLAB program code with Range-Doppler algorithm.

EAST syndrome is autosomal recessive disorder due to mutations in gene KCNJ10, a gene encoding a potassium channel expressed in the brain, eye, ear and kidney. It is characterized by four cardinal features; Epilepsy, Ataxia, Sensorineural deafness, and renal salt-wasting Tubulopathy, thus the acronym EAST syndrome. It was rst described as a distinct clinical entity in 2009 by Bockenhauer and scholl, who named this condition EAST syndrome and SeSAME syndrome for Seizures, Sensorineural deafness, Ataxia, Mental retardation and Electrolyte imbalance respectively. Neurodevelopmental delay is evident in most patients with EAST syndrome that were old enough to be assessed; Thus, physiotherapy intervention also plays a vital role in EAST syndrome along with medical management. From physiotherapy perspective; symptomatic management to Improve overall health, wellbeing and motor control becomes ultimate goal in the patient with EAST syndrome. As there is no specic physical therapy treatment approach and no specic tool to evaluate function for children with EAST syndrome; for clinically presented delay development and ataxia, Neurodevelopment therapy (NDT) was utilized as treatment approach and Gross motor function measure (GMFM) & Gross motor performance measure (GMPM) were utilized for assessment in this case study to track progress on follow ups. Result showed marked improvement in GMFM and GMPM scores at follow ups and concluded that Physical therapy intervention improves the gross motor function as well as gross motor performance in patient with EAST syndrome.
