Path Planning with Modified RRT* Algorithm for Lung Biopsy

Path planning plays a central role in robot-assisted percutaneous insertion.The main challenge of path planning exists in the motion constraints inherited from the geometry and mechanics of the needle, and the complex anatomic environment of human body.In nonholonomic planning, the classic Rapidly-Exploring Random Trees (RRT) algorithm may fail to provide a continuous and obstacleavoidable path.To find a feasible path and minimize the damage on soft tissues based on a newly-introduced curvature-controllable steerable needle, we propose a method that utilizes RRT* and quadratic Bezier curve smoothing technique.RRT* with Bezier Curve Smoothing can generate a path composed of smooth piecewise planar curves with continuous connections.Comparisons are employed to show that our method generates shorter and less torturous paths with a higher success rate.

What is examined in this study is the application of learning with the Student Teams Achievement Division (STAD) model, the improvement of student learning outcomes, and how active student learning is during the learning process. This study uses observations to determine the learning process of Student Teams Achievement Division (STAD) and to determine student learning activeness, and tests to determine student learning outcomes. From the results of this study, it was found that: (1) The learning process using the Student Teams Achievement Division (STAD) model is as follows: Stage 1: Group formation, Stage 2: Teaching, Stage 3: Study Team, Stage 4: Tests / Quizzes, Stage 5: Recognition; (2) By applying the Student Teams Achievement Division (STAD) model, the learning outcomes of class XII IPA 3 MAN 1 Tegal in the odd semester of the 2019/2020 academic year subject to mathematics have increased from the initial conditions, the first cycle, and the second cycle. The increase is as follows: In the initial condition there were 55% of unfinished students, 45% of students who had completed. In the first cycle, there were 29% of students who had not completed, and there were 71% of students who had completed. In the second cycle, there were 14% of students who had not completed, while there were 86% of students who had completed. Thus until the second cycle, students whose learning outcomes were complete reached more than 85%; (3) The activeness of students during the learning process from the first and second cycles increases, namely as follows: In the initial conditions (a) students with low activity 66%, medium activeness 18%, high activeness 16%. In the first cycle (a) students with low activity 28.1%, medium activeness 41.2%, high activity 30.7%. In the second cycle (a) students with low activity 8.8%, medium activeness 44.7%, high activity 46.5%.
Structuring of Psychological Space and Establishing Hegemony: A Study of Literary and Non-Literary Discourses

This paper looks into how various discourses came into being, how linguistic structures started dominating social as well as individual life and how psychological space is created, which is enlarging continuously. It also deals with the question - how language and literature are used as technology to shape the human psyche? At the surface level, there seems to be no use of technology in language and literature, except in printing and production through audio-visual means. However, the reality is very different. All discourses and other forms of art are technological productions because the arrangement of words, utterances, symbols, expressions and various other things require technical skill. A writer or artist produces his works like a technician who produces machines. That is why there is no doubt that humankind has always made use of language and literature to structure the psyche of people. It manifests itself in the processes how a person agrees to become human bomb, why a person self-immolates for some abstract cause, how soldiers are persuaded to fight for the nation, how people are divided into various social classes, and why they give consent for self-exploitation? Advertisers, politicians, and journalists are aware of the reality more than common masses and therefore they use language in an effective way to get desired response from the masses.
Convergence analysis of cuckoo search algorithm based on martingale theory

Cuckoo search (CS) algorithm is an emerging kind of biologically inspired algorithm that has been successfully applied in several areas. However, its mathematical theory has not yet been fully established up to now, and the theoretical analysis of convergence is relatively inadequate. In this article, the martingale theory is introduced for the first time to prove the convergence of CS, which replaces the ergodic analysis of the Markov chain. First of all, according to the basic principles of CS, we establish the mathematical model of the Markov chain and group state sequence, and its Markov properties are analysed, and then the optimal group state set is obtained. After that, the supermartingale of the cuckoo evolution sequence with an optimal fitness value is derived. In the end, based on the convergence theorem of supermartingale, it is demonstrated that the CS algorithm ensures global convergence.
Study on improvement effect of waterborne two-component polyurethane on radioactive pollution of building decoration materials

In order to improve the removal effect of radioactive concentration of building decoration materials, this paper improves the radioactivity of building decoration materials by preparing waterborne two-component polyurethane coating and coating it on the surface of building decoration materials. The reaction mechanism of two-component waterborne polyurethane was analysed. The content of -NCO in prepolymer samples at a certain time point was determined by Hydrochloric acid - din-butylamine method. The waterborne two-component polyurethane coating was prepared based on IPDI based curing agent and coated on the surface of radioactive building decoration materials to effectively reduce the radioactivity of building decoration materials, realise the improvement of radioactive pollution of building decoration materials. The experimental results show that the radioactive concentration of building decoration materials treated by this method is only 2.86 Bg/kg. This method can improve the radioactive pollution of building decoration materials.
A concept for weighting sentiment phrase using deterministic solution of algebraic equations

Many text mining methods have used statistical information as text and language-independent procedures that are not deterministic.On the other hand, grammatical structure-based methods are limited to use in a certain language and text.We aim to suggest an algorithmic algebraic equation in a deterministic and nonprobabilistic way while maintaining the advantage of language independence.We propose a mathematical approach that transforms text and labels into a set of dumb equations.By solving the equations, each word is assigned a weight that can reflect the semantic information of that word, then we use the proposed algorithm to build a novel sentiment dictionary.We propose a purely mathematical approach to remove less informative tokens preprocessing steps and to pay attention to specific semantically rich words and contents.This is done by applying automatic weight allocation capability to understand each word's meaning in the user's notes in various texts.Solving a set of dumb equations is one of the strengths of the proposed algorithm.Finally, we evaluated the proposed algorithm in a sentiment analysis (SA) case study, and the Taboada database and its capability and efficiency in weight allocation and creation of automated dictionaries have been demonstrated.The numerical results show up to 15% of improvement in all parts of the database compared to existing methods.
Using Oblique Elimination to Solve Elliptic Curve Discrete Logarithm Problem

The elliptic curve discrete logarithm problem is believed to be a secure cryptographic primitive for over three and a half decades. This problem was reduced to a problem in linear algebra problem by a Las Vegas algorithm. That algorithm was presented in IndoCrypt 2018. It was further shown that the linear algebra problem can be solved by zero minors. In this paper, we propose oblique elimination as a way to solve the elliptic curve discrete logarithm problem. This paper provides an improved version of the oblique elimination algorithm along with an example. This paper also provides an implementation of the oblique elimination algorithm.
Recognizing Emergencies and Multi-User Behavior Patterns Using Imperfect Data from Distributed Access Points

Human posture, localization and tracking can be estimated by using WiFi signals and traces. However, this kind of application can be controversial due to privacy concerns. We claim that it is possible to assess situations with simple data aggregation without hindering citizens’ privacy. In this paper, we propose an easy-to-implement approach to aggregate data from logs of multiple distributed WiFi access points (APs) to perform multi-user activity recognition. The approach does not include any type of tracking or meta-data analysis. We gathered raw data from the eduroam WiFi network of a building on Polytechnique Montreal’s campus and applied supervised and anomaly detection techniques to first recognize events of academic activity based on people’s behavior. Next, based on the occurrence of an evacuation drill, we were able to show that the methodology provides a preliminary way to evaluate and detect emergency situations. We obtained excellent results in discriminating the occurrence of the targeted human behavior. We found that aggregating data in time bins using common baseline statistics as well as estimates of higher-order moments and derivatives was useful to capture patterns, even in a situation where only 10% of the WiFi APs’ data was assumed to be available. The evacuation drill’s dynamics were recognized with an ROC AUC of 99% using binary classification techniques and with an ROC AUC of 70% using anomaly detection. Stringent conditions were self-imposed to ease the generalization of the technique. No efforts were made on the logs, which are known to be noisy and susceptible to information loss. Being able to achieve early detection of multi-user behavior, without relying on video, has tremendous potential for the management of emergencies that have a tendency to provoke stampedes. We hope this work motivates stakeholders to gather data regularly so that when emergencies take place, we can further research the ways in which we can take advantage of this type of technique.
Student Opinions on the Use of High-Tech Mobile Devices in the Design of Digital Games for Learning

Schools have adopted digital technologies as a strategy for learning and teaching activities because it offers opportunities for scaffolding. This strategy has been implemented in conjunction with creative activities. In addition, activities based on digital games, known as digital game-based learning (DGBL), and various mobile technologies, have been piloted in schools over the past few years to develop innovative learning. The purpose of this research is to investigate how children's collaborative interactions develop while participating in activities requiring them to solve problems utilizing intelligent and mobile technology. Our research combines theoretical viewpoints on joint participation, affordances, and a sense of community in the context of collaborative interactions. This is done with a contextual perspective on learning as its starting point. The following are some of the questions posed in this research: (1) How do children's digital game design activities drive and support collaborative interactions while they are engaged in problem-solving activities? Furthermore, (2) How do children's ideas for designing digital games manifest themselves during activities involving the design of games that involve innovative mobile technology? The study is based on a case where a creative workshop was held with 22 Swedish third-grade children aged 9 to 10 years old who participated in game design activities in a pedagogical lab. When the children worked together to solve the problem of designing and producing a joint digital game idea using mobile technology, a sense of community emerged due to their efforts. The study's results were analyzed using a thematic approach, which revealed that the children used different orientations in their collaborative interactions. Based on this, we argue that it is crucial to be aware of the pedagogical context when preparing for educational activities that involve innovative mobile technology. This is because the pedagogical context is the aspect of the design that creates meaningful collaborative interactions, and it is only then that innovative mobile technology becomes smart. These findings have significant ramifications for the methodological field of incorporating cutting-edge mobile technology into various types of educational settings
Natural Human Interaction - The Future of Social Media

In the future, major social networks will become personal “Social Dashboards”, being at the core of people’s lives in the global village. Human Relationships will no longer be as physically dependent and we will befriend and hang out with people from all over the world and all walks of life, all ethnicities and all beliefs, creating a worldwide melting pot. All the same, the future is anything but information overload. The future is information customization. There will be no need to search for information. The information will find us. It will be specially tailored to individual interests and needs, saving all a lot of time, effort and energy. There will be no difference between a physical and a digital world. There will be no division between user experience and consumer experience. There will be a human experience. The future of social media is natural human interaction, pure and simple.
Discrete and Deterministic Planning

PDDL supports the expression of several different classes of planning problems. In this chapter and the next, we begin with the simplest class of planning problems, which are discrete, finite, and deterministic. This kind of planning is often called classical (to distinguish it from the many different extensions that have later followed).

The results of this study show the application is able to display the location of the patchwork of the tire that is open, the application can help the Rider to call the Tire Patcher to the location, and GIS technology is successfully applied to determine the position of the Rider and the route to the location of the tire patch, and vice versa
POTENSI LUMBROKINASE DENGAN CARRIER N,N,N-TRIMETIL KITOSAN KLORIDA (TMC) MENGGUNAKAN LIGAND C-RGD SEBAGAI AGEN FIBRINOLITIK DAN ANTI-PLATELET TERBARUKAN

Introduction: Venous thrombosis is the third most cardiovascular disease in the world. Administration of fibrinolytic agents such as streptokinase is the chosen treatment of the disease. However, the disadvantages are short half-time, unspecific to fibrin, poor targeting, expensive price, and tend to cause bleeding. Therefore another fibrinolytic agent is needed to cope with some of the deficiencies and side effects of current fibrinolytic agents. This literature review aims to explain the potential of lumbrokinase with TMC carrier and c-RGDligand as a renewable fibrinolytic and antiplatelet agent. The method used in this literature review is a literature study using the last 10 years of journal gained from some search engines such as ScienceDirect, PubMed, Google Scholar, and ClinicalKey.&#x0D; Discussion: Lumbrokinase is an enzyme from the extraction of the earthworm’s digestive tract which consists of several serine protease isoenzymes. As a fibrinolytic agent, lumbrokinase can hydrolyze both fibrin or fibrinogen and also activate plasminogen into plasmin. Besides, lumbrokinase is known as has an antiplatelet effect as aspirin has. The use of TMC as the carrier can increase the bioavailability of lumbrokinase. Meanwhile, the addition of c-RGD ligand can increase the specificity preventing fibrinogen to bind the GPIIb/IIIa receptor thereby inhibiting thrombus formation.&#x0D; Conclusion: From various in vitro and in vivo studies, it was concluded lumbrokinase with carrier TMC and c-RGD ligand can accelerate thrombolysis, and reduce the risk of bleeding so that it’s potentially a renewable fibrinolytic and antiplatelet agent. However, further research is needed regarding therapeutic doses, side effects, and toxicity studies.
SISTEM APLIKASI ANDROID PENCARIAN MULTI TEKS PADA TUJUH KITAB HADIS MENGGUNAKAN ALGORITME KNUTH-MORRIS-PRATT

Hadith according to Ibnu Taimiyah is something that comes from the Prophet Shallallahu ‘Alaihi wa Sallam which consists of words, deeds and taqrir. With the increasingly rapid development of information technology in today's world, Muslims can use it to study various sciences, including knowing the meaning of the contents of the hadith for guidance in daily life. One way that can make it easier is to use an Android-based application. In previous research, the multi-text search system on seven hadith books can search for hadiths from seven hadith books and is equipped with the Correct Spelling feature. However, the system that has been developed can only be accessed using a web browser, so the authors developed a multi-text search system on the seven hadith books based on Android to increase user interaction with the search system for the seven hadith books. The research stages used the Waterfall Method because the stages of the work were coherent. The hadith data used in the study were 52,618 hadiths in the database. Making system design using Unified Modeling Language modeling. The coding is done using the PHP and Java programming languages by applying the Knuth-Morris- Pratt Algorithm. Testing using Black Box Testing is a test whose testing process is derived from the program or component specifications. This Android-based system provides a better experience to users with an attractive appearance. The search results in the system use keyword weighting in the hadiths that are searched. Based on the results of the system development research, it was concluded that the multi-text search system on seven hadith books based on Android has been successfully developed and the results of testing the hadith search feature using categories make the search for hadiths more efficient.
