На материале произведений современной татарской писательницы Р. Габдулхаковой выявляются конститутивные черты жанра парча в современной татарской литературе. Охарактеризованы жанровые разновидности парчи в творчестве Р. Габдулхаковой, которые соответствуют двум направлениям сюжетного движения: от внешнего к внутреннему или от единичного к универсальному и двум типам повествования - от 1-го или от 3-го лица. Художественное завершение в парчах первого типа определяется постижением некой нравственной истины, вытекающей из лично пережитой лирическим субъектом ситуации, в парчах второго типа оно создается переходом от отдельных явлений к их суммирующему итогу. Сделан вывод о том, что внутреннюю меру жанра определяет характер соотношения повествовательной фабулы и обобщающей ее «концовки». Описаны свойственные этому жанру пространственно-временные отношения и принципы организации субъектной сферы. Структурообразующая роль в парчах Р. Габдулхаковой отводится субъективно-лирическому началу в повествовании. В произведениях писательницы проявились как особенности ее творческой индивидуальности, так и типологические черты женской прозы в целом с ее повышенной эмоциональностью, автобиографичностью и проникновенностью. Большинство миниатюр Р. Габдулхаковой написаны от первого лица и представляют сознание женщины, сосредоточенной на переживании своего одиночества и «холода жизни», безответной любви и позднего раскаяния, боли утраты, преследующей каждого человека после ухода матери. Парчи, написанные от третьего лица, раскрывают сознание человека, знающего о существовании объективных закономерностей и пытающегося найти личный выход из безнадежных ситуаций. В творчестве Р. Габдулхаковой парча функционирует как синтетический жанр, вбирающий в себя элементы других жанровых форм. On the material of works of the modern Tatar writer R. Gabdulhakova the constitutive features of the genre of the parcha are revealed. Genre varieties of parcha in the work of R. Gabdulkhakova are characterized, which correspond to two directions of plot movement: from the external to the internal or from the individual to the universal, and two types of narrative-from 1 or 3 persons. Artistic completion in the parcha of the first type is determined by the realization of a certain moral truth arising from the situation personally experienced by the lyrical subject, in the parcha of the second type it is created by the transition from individual phenomena to their summing result. It is concluded that the internal measure of the genre determines the nature of the relationship between the narrative plot and its generalizing "ending". Space-time relations and principles of organization of the subject sphere peculiar to this genre are described. The structure-forming role in the parcha of R. Gabdulkhakova is assigned to the subjective-lyrical beginning in the narrative. The works of the writer manifested both the features of her creative individuality and the typological features of female prose in general with its increased emotionality, autobiography and penetration. Most of R. Gabdulhakova’s miniatures are written in the first person and represent the consciousness of a woman focused on experiencing her loneliness and “cold life”, unrequited love and late repentance, the pain of loss that haunts every person after leaving her mother. Рarcha written in the third person reveal the consciousness of a person who knows about the existence of objective laws and tries to find a personal way out of hopeless situations. Allegorical or symbolic imagery at the same time turns a personal scenario - into a typical, universal human one. In the work of R. Gabdulhakova parcha functions as a synthetic genre, incorporating elements of other genre forms.

AbstractIn this work, a low-priced smart fabric forcesensing glove is developed which is able to measure the total amount and direction of the force a person applies on a patient in a physiotherapeutic context. A device like this would be beneficial for the education of physiotherapists, to measure the progress of a patient and to evaluate the treatment. The proposed device uses a new sensor, which is based on a piezoresistive fabric. This fabric changes its electrical resistance according to the applied stress. The characterization of this sensor revealed that the change in resistance of the sensor is dependent of the amount of force, the loaded area, the total time the sensor is loaded and hysteresis. To compensate these behaviours, an additional sensor based on the same smart fabric was developed which measures the loaded area of the first sensor. By combining these two sensors, it is possible to calculate the applied force. The results show the feasibility to build a measurement system out of smart fabric material that can measure the applied force. Furthermore, the prototype shows promising results in determining the applied force in amount and direction.

The Way

Silver nanoparticle angle sensors are inkjet printed on a flexible PET substrate and implemented as pairs of compression and tension side folding individuals into a rigid experimental setup. Resulting combined signals improved the individual sensor responses due to their compensating characteristics, and gave the best performances in the existing literature in terms of linearity, sensor life-time, static and cyclic drift, hysteresis and dynamic dependency. Proposed method is promising for eliminating the major limitations on the printed sensor use in flexible hinges and paving the way to fully soft all-integrated foldable robots.

Abstract Background: On December 31, 2019, multiple pneumonia cases, subsequently identified as coronavirus disease 2019 (COVID-19), was reported for the first time in Wuhan, the capital city of Hubei province in China. At that time, the Wuhan Municipal Health Commission had report 27 cases, of which seven are severely ill, and the remaining cases are stable and controllable. Since, then, the spread of COVID-19 has already taken on pandemic proportions, affecting over 100 countries in a matter of weeks. As of September 07, 2020, there had been more than 27 million confirmed cases and 889,000 total deaths, with an average mortality of about 3.3%, globally. In Ethiopia, 58,672 confirmed cases and 918 deaths and this number are likely to increase exponentially. It is critical to detect clusters of COVID-19 to better allocate resources and improve decision-making as the pandemics continue to grow.Methods: We have collected the individual-level information on patients with laboratory-confirmed COVID-19 on daily bases from the official reports of the Ethiopian Federal Ministry of Health (FMOH), regional, and city government of Addis Ababa and Dire Dawa health bureaus. Using the daily case data, we conducted a prospective space-time analysis with SaTScan version 9.6. We detect statistically significant space-time clusters of COVID-19 at the woreda and sub-city level in Ethiopia between March 13th-June 6th, 2020, and March 13th-June 24th, 2020.Results: The prospective space-time scan statistic detected “alive” and emerging clusters that are present at the end of our study periods; notably, nine more clusters were detected when adding the updated case data.Conclusions: These results can notify public health officials and decision-makers about where to improve the allocation of resources, testing areas; also, where to implement necessary isolation measures and travel bans. As more confirmed cases become available, the statistic can be rerun to support timely surveillance of COVID-19, demonstrated here. In Ethiopia, our research is the first geographic study that utilizes space-time statistics to monitor COVID-19.

The Individual

The timeline or track of any individual, mobile, sentient organism, whether animal or human being, represents a fundamental building block in understanding the interactions of such entities with their environment and with each other. New technologies have emerged to capture the (x, y, t) dimension of such timelines in large volumes and at relatively low cost, with various degrees of precision and with different sampling properties. This has proved a catalyst to research on data mining and visualizing such movement fields. However, a good proportion of this research can only infer, implicitly or explicitly, the activity of the individual at any point in time. This paper in contrast focuses on a data set in which activity is known. It uses this to explore ways to visualize large movement fields of individuals, using activity as the prime referential dimension for investigating space—time patterns. Visually central to the paper is the ringmap, a representation of cyclic time and activity, that is itself quasi spatial and is directly linked to a variety of visualizations of other dimensions and representations of spatio-temporal activity. Conceptually central is the ability to explore different levels of generalization in each of the space, time and activity dimensions, and to do this in any combination of the (s, t, a) phenomena. The fundamental tenet for this approach is that activity drives movement, and logically it is the key to comprehending pattern. The paper discusses these issues, illustrates the approach with specific example visualizations and invites critiques of the progress to date.

Lower extremity weakness is a serious problem afflicting people all over the world. Until recently, the mobility options for people with this condition have been confining and limit the individual’s functionality. Walking assist devices are presently in development to restore hands-free walking to people with lower extremity weakness. These devices provide the necessary support and power to enable the individual to restore normal ambulation. The proposed design of exoleg, a single leg external walking assist device, addresses the demographic of people with lower extremity weakness. The design includes replication of the gait cycle utilizing mechanical links and user control interface with emphasis on safety. The design couples the actuation of the knee and hip through the use of linkages connected to a single motor. The actuation of the hip is controlled by a 4 bars crank-rocker linkage system while the knee is actuated by corresponding linkages (designed in WORKING MODEL 2D, a commercial simulation software) that generates the knee kinematic profile. The angular profiles of the knee and hip actuations are compared with the actual knee and hip angular trajectories. The frame of the device incorporates a passive ankle stabilization system to compensate for the effects of foot drop. The system utilizes feedback from trigger points from pressure sensors on the foot and goniometers at the hip and knee joints to measure the angulations in gait to keep the device in synchronization with natural ambulation. An on-board microprocessor receives the feedback from the trigger points and sends the actuation signal to the motor. A conceptual design of electrostatic actuator motor is also proposed to keep the device light weight and compact.

Glaucoma Drainage Devices

AbstractGlaucoma is an eye disorder in which the optic nerve is damaged over time due to a sustained elevation of the intraocular pressure (IOP). Being the second leading cause of blindness according to the reports of the World Health Organization, glaucoma is not only a serious ocular disease that threatens individuals, but also a community health problem. In recent years, great improvement has been achieved in the technology of implants used in the treatment of the disease. Despite the great effort dedicated to the design and implementation of the glaucoma drainage devices (GDD), they still have unsolved problems and weaknesses. Most of the currently employed GDDs are very simple and have major problems such as reversed flow, choking and a coarse interval of pressure control. Experiments must be devised to investigate the flow behavior inside these devices. In this study, an accurate microfluidics experimental setup is constructed to analyze and characterize the in-vitro performance of actively employed GDDs on the glaucoma treatment. Proposed setup includes a pressurized fluid reservoir, ELVEFLOW microfluidics flow rate measurement/control unit, microfluidics flow/pressure sensors, and data analysis system. In the setup, more precise measurements than experimental setups in literature is planned to be provided. It is estimated that the results showing consistency with in-vivo measurements will be obtained, behavior of the fluid passing through the GDDs will be observed and issues with design flaws will be addressed.
