RF Vital Sign Sensing under Free Body Movement

Radio frequency (RF) sensors such as radar are instrumental for continuous, contactless sensing of vital signs, especially heart rate (HR) and respiration rate (RR). However, decades of related research mainly focused on static subjects, because the motion artifacts from other body parts may easily overwhelm the weak reflections from vital signs. This paper marks a first step in enabling RF vital sign sensing under ambulant daily living conditions. Our solution is inspired by existing physiological research that revealed the correlation between vital signs and body movement. Specifically, we propose to combine direct RF sensing for static instances and indirect vital sign prediction based on movement power estimation. We design customized machine learning models to capture the sophisticated correlation between RF signal pattern, movement power, and vital signs. We further design an instant calibration and adaptive training scheme to enable cross-subjects generalization, without any explicit data labeling from unknown subjects. We prototype and evaluate the framework using a commodity radar sensor. Under a variety of moving conditions, our solution demonstrates an average estimation error of 5.57 bpm for HR and 3.32 bpm for RR across multiple subjects, which largely outperforms state-of-the-art systems.

Shallot Market Cointegration Between Markets in Province West Southeast and East Nusa Tenggara

West Nusa Tenggara Province is one of the provinces that has become the centre of shallot production in Indonesia, and this situation has made this province, in addition to being able to produce shallots for the needs of its people it is also able to be distributed in other areas, one of which is East Nusa Tenggara Province. And the price of shallots in West Nusa Tenggara Province is much lower than the price of shallots in East Nusa Tenggara Province. The research objective was to determine the long-term relationship between the cost of shallots between Kupang City, Mataram City and Bima City, and the pattern movement of the price of shallots in Kupang City, Mataram City and Bima City. This study uses monthly price data for 2018-2020, the average price of shallots for traditional markets and large traders in the East Nusa Tenggara and West Nusa Tenggara regions. The data analysis method used is the Error Correction Model (ECM) method. This determines whether there is a long-term and short-term relationship between the three markets. The results showed that there was a long-term and short-term relationship between the price of shallots in Bima City and Kupang City, and Mataram City. The situation illustrates that price changes always follow every price change in Mataram in Bima City and Kupang City. Keywords : Shallot, Market, Cointegration, price.

Fabrication of Saddle-Shaped Surfaces by a Laser Forming Process: An Experimental and Statistical Investigation

Laser forming is a powerful tool for fabricating complicated shapes economically. The pattern of laser movement (irradiating scheme) has an essential effect on the shaped form. In this article, the forming of a saddle-shaped surface will be investigated experimentally by the laser forming process. A spiral irradiating scheme is implemented to manufacture a saddle-shaped surface. The main idea of this study is the investigation of the simultaneous variations of the process parameters and their effect on the curvature of the final part. The process parameters of the study are the spiral pitch, number of spiral passes, and movement pattern (In-to-Out or reversely Out-to-In scanning path). The response surface methodology is selected for experimentation. The measurement of the deformation results shows that the deformations of laser-formed saddle-shaped surfaces decrease with an increase in the spiral pitch of the path. Additionally, the deformations of the saddle-shaped surface increase by increasing the number of spiral passes. The results demonstrate that the pattern movement has little effect on the deformations of laser-formed saddle-shaped surfaces and an Out-to-In spiral pattern movement is advised. At last, the proper input variables to obtain the maximum value of displacements for the saddle point are determined (10 mm spiral pitch, three spiral passes, and Out-to-In pattern movement).

ON THE TYPOLOGICAL CLASSIFICATION OF MOTION VERBS IN FINNO-UGRIC LANGUAGES

In this paper, I compare the semantic structure of the Hungarian and Udmurt verbs of motion. I state that, contrary to the general opinion of the typological literature, the semantic structure of Finno-Ugric verbs is not only Motion + Mode (Motion + Co-event). In Udmurt and in the old Hungarian language there are many motion verbs with the pattern Movement + PATH. Today, PATH is encoded differently in Udmurt and Hungarian movement verbs from a typological point of view. Probably the following happened: when the Hungarian verb system was consolidated, PATH was coded with the preverb, and verb-framed motion verbs became satellite-framed motion verbs. This hypothesis requires further research.

Karakteristik Penyeberangan Pada Ruas Jalan Diantara Dua Pusat Perbelanjaan Yang Berhadapan (Studi Kasus Ruas Jalan Raya Margonda Antara Depok Town Square dan Margo City)

The pedestrian is traffic, in the transport system which is dominant in urban areas. Walking characteristics is a major factor in the design, planning and operation of transportation facilities, particularly lzigh demand by the short period. Tiw study was conducted in the area around the commercial area on Highway Margonda Depok, Depok_ Town Square between City and Margo. TI1is research is to analyze pedestrian behavior by microscopic analysis. Microscopic is taken because of to see journey behavior that happened in each individual. By using microscopic can know by characteristic, behavioral, and pattern movement of pedestrian individually. Research microscopically this also can see pedestrian trail individually in time and position, where used variable is N (pedestrian number), T (time), Y and X (Coordinate Location). The study concluded that there was difference in the pattern of female and male pedestrian. VV/ren crossed in groups of women tend to follow the pattern of male.

Conceptual mobility model of vertical handover decision in heterogeneous networks

In heterogeneous network, maintaining seamless connectivity needs excessive efforts from various aspects such as network availability and mobile node reliability. Presently, a vertical handover management is a practical approach in facilitating the service continuity for mobile users. Many researches have been conducted in this area by considering performance improvement in delay, latency, and overhead. Preserving the Quality of Services (QoS) based on user mobility and pattern movement during handover decision has become an important aspect in vertical handover management. This paper presents the conceptual mobility model of vertical handover decision in heterogeneous network. Hence, several researches in vertical handover decision management has been reviewed regarding the issues on the vertical handover decision algorithms such as RSS Based Algorithm, MADM Based Algorithm and Intelligence Based Algorithm. This paper highlights the current decision algorithms that integrate the traditional methods with intelligence algorithm for better optimization. In decision parameters, the user mobility pattern can be importance in terms of direction randomness and mobility speed. Hence, a conceptual mobility-awareness model for vertical handover are been proposed in targeting some improvement of handover performance.

PERSPEKTIF LUKISAN KOOLAM DARI SEGI ILUSTRASI DI BANDAR SUNGAI PETANI, KEDAH (THE ART OF KOOLAM IN SUNGAI PETANI, KEDAH - ILLUSTRATION PERSPECTIVE)

Koolam merupakan lukisan lantai yang amat popular dalam kalangan masyarakat India. Lukisan Koolam bukan melibatkan hiasan semata-mata malah ia merupakan media komunikasi. Dalam kajian ini, lukisan Koolam dikaji dari perspektif ilustrasi. Kajian dijalankan di bandar Sungai Petani, Kedah. Koolam yang menjadi sampel kajian ialah Koolam asas yang diperbuat daripada serbuk beras dengan menggunakan pergerakan tangan yang spontan. Metod yang digunakan dalam kajian ini terdiri daripada kaedah aspek Grounded Theory (teori asas), Phenomenology (fenomenologi), Content Analysis (analisis kandungan), Textual Analysis (analisis teks) dan Semiotics (semiotik). Dapatan kajian membuktikan bahawa Koolam-Koolam asas di bandar Sungai Petani dimulakan dengan titik. Titik ini disamakan dengan ‘pottu’, iaitu tanda yang terdapat pada dahi kaum wanita India. Titik-titik pada kolam kemudian disatukan agar berbentuk pelbagai jenis garisan yang kemudiannya membentuk Koolam dua dimensi dan tiga dimensi. Koolam-Koolam di Sungai Petani terdiri daripada unsur seni, iaitu ruang, warna asas dan tekstur yang sempurna. Prinsip asas yang terdiri daripada corak, pergerakan, keseimbangan, proposi, harmoni dan penekanan dalam lukisan kolam jelas kelihatan pada Koolam-Koolam di bandar Sungai Petani, Kedah. Kajian ini diharapkan dapat memberikan pendedahan dan pengalaman baharu kepada generasi baharu yang hanya melihat Koolam sebagai lukisan perhiasan. (Koolam is a form of drawing that is done on the floor and is very popular in the Indian community. It is not merely meant to be decoration, but a form of communication. In this study, Koolam is researched from the illustration perspective. The study is carried out in Sungai Petani,Kedah. The Koolams that are the samples in this research are the basic forms and are drawn with spontaneous hand movements using rice in the form of powder. The method that are used in this study are Grounded Theory (the basic theory), Phenomenology, Content Analysis, Textual Analysis and Semiotic. The findings of the study on the basic 'Koolams' in the Sungai Petani town shows that they are drawn with a dot. The dot is equated to the dots that are found on the Indian women's forehead, which is known as the Pottu. These dots are then joined with various lines, that will form two or three dimentional Koolams. They also contain the art elements, which are the space, basic colours, and the perfect structure. Furthermore, the basic principles such as pattern, movement, balance, proportion, harmony, and emphasis are obviousin the Koolams that are found in the Sungai Petani, town in Kedah. This research was carried out with the aim of giving exposure and experience to the new generation, so that it is not just seen as a piece of decorative art.)

Relevant Canonical Genre Families

The basis for a functional communication perspective for elicitation strategies is a selection of generalised high-value genres referred to as canonical genres. There are a number of families of genre but those that are of particular relevance to interviewing and interview protocols are the so-called factual and narrative genre families. The purpose of the chapter is to describe each of these in turn. Following the software engineering pattern movement, each genre that belongs to these families will be described using a common format: a name (capitalized as is convention for genres in SFL), a description, a genre element inventory or a table that provides the list of the genre elements codes, names and function, the corresponding genre digraph, and an authentic transcript marked up with genre stages. The transcripts used to exemplify these canonical genres, reveal a range of unusual features unpacked in more detail in the next chapter.
