Abstract. Background: Identifying precursors that will aid in the discovery of individuals who may harm themselves or others has long been a focus of scholarly research. Aim: This work set out to determine if it is possible to use the legacy tokens of active shooters and notes left from individuals who completed suicide to uncover signals that foreshadow their behavior. Method: A total of 25 suicide notes and 21 legacy tokens were compared with a sample of over 20,000 student writings for a preliminary computer-assisted text analysis to determine what differences can be coded with existing computer software to better identify students who may commit self-harm or harm to others. Results: The results support that text analysis techniques with the Linguistic Inquiry and Word Count (LIWC) tool are effective for identifying suicidal or homicidal writings as distinct from each other and from a variety of student writings in an automated fashion. Conclusion: Findings indicate support for automated identification of writings that were associated with harm to self, harm to others, and various other student writing products. This work begins to uncover the viability or larger scale, low cost methods of automatic detection for individuals suffering from harmful ideation.

Muscle pain can be elicited by any irritation of the nociceptors in the muscle or central sensitization in the central nervous system and represent a challenge for medical as well as for neurological rehabilitation. The most frequently described muscle pain syndromes are myofascial pain syndrome (MPS) and fibromyalgia syndrome (FMS). The use of infrared thermography in rehabilitation medicine for assessment of musculoskeletal disorders is not well documented in the current literature. This study is focused around MPS due to the more localized manifestations of this syndrome and it’s objective is to asses a correlation between the clinical findings, ultrasound examination and the thermal pattern of trigger points.

Abstract Total Knee Arthroplasty is one of the most commonly performed orthopedic procedures and it is expected to grow in the next future. In the last past years, computer-assisted procedures represent one of the trends that are transforming the way of practicing medicine. Cornering the Total Knee Arthroplasty, digital models of the joints have been used to carry out simulation of their kinematics and mechanical performance. Whilst for the 3D digital reconstruction of the patient geometry several studies have been conducted, an approximated geometry of the prosthesis has been several times employed, with undeniable consequences on the final results. This paper aims at comparing two non-contact reverse engineering technologies to acquire the shape of femoral components employed for total knee arthroplasty. A high-level device (Konika Minolta Vivid 9i) and a mid-low cost laser (NextEngine) has been compared. For the comparison, a systematic procedure of acquisition and elaboration of the results has been adopted in order to have as unbiased as possible results. The procedure involves the use of the proprietary software of the scanners for the elaboration of the raw data and the meshing procedure has been kept the same for all the models. Since the as-is acquired mesh is of high-resolution, a decimation procedure has been carried out in order to make the 3D models lighter and easier to be handled. Once the decimation procedure has been evaluated comparing the original and the simplified models to one another, the digitalized models have been compared with the measurements taken from a coordinate measuring machines. As a preliminary result, the two lasers seem to be adequate to accomplish the reverse engineering process as required by this application. Of course, the mid-low cost laser would be preferable whether the performance will be confirmed to be (statistically) equal.

AbstractThis paper introduces new research that seeks to develop low-cost, high quality, mass customizable building assembly systems that provide visually rich design variations for housing or other small structures. The building systems are intended to be tailored for particular cultures and communities by incorporating vernacular decorative design into the assembly design. Two complementary research areas are brought together in this work: shape grammars and digital fabrication. The visual, aesthetic aspects of the research are explored through shape grammars. The physical design and manufacturing aspects are explored through advanced digital design and fabrication technologies, and in particular, build on recent work on monomaterial assemblies with interlocking components that can be fabricated with computer numerical control machines and assembled easily by hand. The long-term objective of this research is the development of formal, visual–physical grammars with rules that generate complete computer-assisted design/computer-assisted manufacturing data for fabrication of full-scale components for assembly design variations. This paper reports on the first phase of this research: pilot studies for prototype assembly systems that incorporate vernacular languages from different parts of the world. The results of these studies are very promising, and demonstrate a spectrum of strategies for embedding visual properties in structural systems. Important next steps in this research are outlined. If successful, this work will lead to new solutions for low-cost, easily manufactured housing, which is especially critical in developing countries and for postdisaster environments. These new housing solutions will not only provide shelter but also support important cultural values through the integration of familiar visual design features. Beyond the specific context of housing and building assemblies, the research has the potential to impact the design and manufacture of designed artifacts on many scales and in many domains, especially in domains where visual aesthetics need to be considered jointly with physical, structural, or material requirements, and where design customization and variation is important.

On Islamic education for students of SMK Elektronika, it has been done summary material about application with image brands (brand image) Easily Applicable Graphical Layout Editor (EAGLE) by literacy approach. EAGLE application is one of the principals of fundamental Islamic education in the material form. The literacy of EAGLE application material, including general explanation and important notes to the EAGLE application. A common explanation of the EAGLE application which is one of the many applications for the draft in the manufacture of pieces of printed boards (printed cicuit board, PCB) computer-assisted (computer aided design, CAD), so as layout editor is easy to use to help draft board printed circuit (PCB). EAGLE application consists of three main modules, namely the Layout Editor, Schematic Editor, and Autoroutes embedded in a single user interface. All three can be accessed from EAGLE's User Interface (UI) or user interface on EAGLE application, so there is no need to change netlists between the scheme and layout. Some advantages of the EAGLE application, namely (i) cross-program (cross platform), where EAGLE can operate on the operating system (Operating System), either Windows, Mac, or Linux, (ii) the need for storage is small, there are editions free use (free of charge) or can also have the low cost, and (iii) support of the community.

Medical navigation providing intraoperative localization of medical instruments plays a crucial role in computer assisted surgery (CAS). Several different multiple- camera standalone optical localizers are available on the market nowadays. Our aim was to develop, easy-to-use, low-cost and portable medical localizer based on iPhone 6S camera. We decided to develop a specialized smartphone app which is able to detect two rigid bodies (RB) on the camera screen and estimate their position both in devices and global coordinate system using sensor fusion with smartphones accelerometer and gyroscope. In the procedure one RB serve as reference and the other is attached to the tool. The prototype was preliminary calibrated using 2D and 3D VDI/VDE 2634 standard. Validation procedure involved measurements of the position and distance of two RBs placed 500 mm from each other in a distance of 1 meter to the smartphones camera. The measurements were taken from three different angles: -30°, 0°, 30° regarding RBs plane. The standard deviation of the measured distance was 0.62 mm with average measured distance of 498.0 mm. The other tests were made in a test-setup where the virtual offset of ultrasound probe was added to one of the RBs so the distance between probe and reference was 195 mm. The tests showed that the position of ultrasound probe is estimated with standard deviation of 0.70 mm and the average measured distance is 195.18 mm. Due to the promising results of those evaluations, we plan to perform more specific tests in clinical setup in near future.

Invasive species spread rapidly and their eradication is difficult. New methods enabling fast and efficient monitoring are urgently needed for their successful control. Remote sensing can improve early detection of invading plants and make their management more efficient and less expensive. In an ongoing project in the Czech Republic, we aim at developing innovative methods of mapping invasive plant species (semi-automatic detection algorithms) by using purposely designed unmanned aircraft (UAV). We examine possibilities for detection of two tree and two herb invasive species. Our aim is to establish fast, repeatable and efficient computer-assisted method of timely monitoring, reducing the costs of extensive field campaigns. For finding the best detection algorithm we test various classification approaches (object-, pixel-based and hybrid). Thanks to its flexibility and low cost, UAV enables assessing the effect of phenological stage and spatial resolution, and is most suitable for monitoring the efficiency of eradication efforts. However, several challenges exist in UAV application, such as geometrical and radiometric distortions, high amount of data to be processed and legal constrains for the UAV flight missions over urban areas (often highly invaded). The newly proposed UAV approach shall serve invasive species researchers, management practitioners and policy makers.

Computer-assisted telephone interviews (CATI) through mobile phones are a low-cost, rapid and safe way to collect data. However, decisions for how such mobile phone surveys are designed and implemented, and their data analysed, can have implications for the sample reached, and in turn affect the generalisability of sample estimates. In this practice paper, we propose a framework for extending the use of CATI–mobile phone surveys in India, which can be applied broadly to future surveys conducted using this method. Across the stages of design, implementation and analysis, we outline challenges in ensuring that the data collected through such surveys are representative and provide recommendations for reducing non-coverage and non-response errors, thereby enabling practitioners in India to use CATI–mobile phone surveys to estimate population statistics with lower bias. We support our analysis by drawing on primary data that we collected in five mobile phone surveys across nine Indian states in 2020. Our recommendations can help practitioners in India improve the representativeness of data collected through mobile phone surveys and generate more accurate estimates.
