Transputer Neuro-Fuzzy Controlled Behaviour-Based Mobile Robotics System

Occam language enables programs to be written as a collection of self-contained programs (tasks) which may be executed simultaneously (parallel or concurrent) or simply one after another with a built-in inter-process communication mechanism, depending whether these processes are executed on a single machine or on separate ones. Occam is a high-level language, it can be viewed as the assembly language for the Transputer. Unlike most microprocessors, e. g., the M68000, the definition of the operations of the Transputer is in terms of the Occam model and not machine language. Besides being a high performance microprocessor (half the speed of a VAX 8600), the Transputer has on its chip four (4) serial bi- directional links (each 20 Megabits per second) to provide concurrent message passing to other Transputers. The “channels” in the Occam language are mapped to these hardware links which connect by way of twisted pairs of wires to other Transputers. Transputer hardware supports concurrency by scheduling (time-slicing), in round-robin fashion, an arbitrary number of Occam concurrent processes. The language and the hardware are so designed that an Occam program consisting of a collection of concurrent processes may execute on one Transputer (via time slicing between the different concurrent processes) or be spread over many Transputers with little or no change in the Occam code. Consequently, the designer can build up his Occam program on one Transputer, and if higher performance is required, can spread the Occam processes over a network of interconnected Transputers. The original Transputer (T414), having no floating point unit and only 2 Kbytes of RAM. Inmos has developed a new, faster version of the Transputer called the (T9000). The T9000 is a 150 MIPS microprocessor with a 20 MFLOPS floating point unit.

Continuous implicit authentication for mobile devices based on adaptive neuro-fuzzy inference system

Continuous implicit authentication for mobile devices based on adaptive neuro-fuzzy inference system

In this section, the structure of our system and function- alities of each component are described. The structure of ANFIS-based implicit authentication system is presented in Fig. 2 which includes an activity monitoring module, a scor- ing module, a reference computation module and an ANFIS module. The learning capability of ANFIS allows for training of specific fuzzy inference model based on given input-output user data without manual interference. Therefore, this trained fuzzy model represents well the user’s behaviour and can then be used to make final authentication decision to provide access control. The deployment of the system can be divided into two phases: training phase and deployment phase. During the training phase, we use generated input (scores, references) and output (classification labels) variables to train ANFIS module offline. When the training is completed the deployment phase starts, this enables the system to infer the authenticity of the current user behaviour by taking in real-time computed scores and references.

Predicting potential of controlled blasting-induced liquefaction using neural networks and neuro -fuzzy system

Predicting potential of controlled blasting-induced liquefaction using neural networks and neuro -fuzzy system

Field blast tests of performance on the real scale have high costs and many limitations. Moreover, results of experimental models show great dependency on site conditions and experiment method. Under these conditions, statistical methods and AI-based methods (articial neural networks and fuzzy systems) with available data have opened up a new world for researchers. Articial neural network and neuro-fuzzy system, despite its low cost (relative to experimental methods used to predict blast-induced liquefaction), are ecient and reliable methods in data processing, even despite various eective parameters and their complex relations.

Classical control has not been able to satisfy the high accuracy of the control request. So in this, combination of the intelligent control with the microcontrollers is proposed. The fuzzy control transforms the control policy indicated by the human natural language into the digital or mathematical function through the fuzzy set and the fuzzy inference, and then uses the computer to realize the predetermined control.

MICROTUBULE BASED NEURO FUZZY NESTED FRAMEWORK FOR SECURITY OF CYBER PHYSICAL SYSTEM

MICROTUBULE BASED NEURO FUZZY NESTED FRAMEWORK FOR SECURITY OF CYBER PHYSICAL SYSTEM

While tending to the semantic gap, one thought is the joining of nearby security strategies. While frequently dismissed in academic research, a crucial perception about operational networks is the extent to which they vary: Numerous security limitations are a site-particular property. Action that is fine in an academic setting can be banned in an endeavor network, and even inside a solitary association, division approaches can contrast generally. In this manner, it is urgent to suit such contrasts. For an abnormality detection system, the characteristic strategy to address site-specifics has the system “learn” them amid preparing with typical traffic. In any case, one cannot just affirm this as the answer for the subject of adjusting to various locales; one needs to expressly demonstrate it since the center issue worries that such varieties can demonstrate assorted and barely noticeable. Lamentably, as a rule, security strategies are not characterized freshly on a specialized level. For instance, a domain may tolerate shared traffic that the length of it is not utilized for conveying improper substance and that it stays, “underneath the radar” regarding volume. To report an infringement of such a strategy, the intrusion detection system would need a thought of what is considered “suitable” or “horrifyingly extensive” in that specific environment; a choice out of span for any of today’s systems. Reporting only the utilization of P2P applications is likely not especially valuable unless the earth level out bans such use. As far as we can tell, such dubious rules are really regular in numerous situations, and in some cases, begin in the uncertain lawful dialect found in the “terms of administration” to which clients must concur. The fundamental test with respect to the semantic gap sees how the components the oddity detection system operates on identify with the semantics of the network environment.

A Neuro Fuzzy System for Modeling the Depression Data

A Neuro Fuzzy System for Modeling the Depression Data

Health informatics (HI) is an interdisciplinary domain, which attempts to merge ‘Healthcare’ and ‘Technology’, effectively. In addition to e-Health (i.e., applications of Information Communication Technology in healthcare delivery [1]) and genomic research (applications of bioinformatics for disease diagnosis and control [2]), one developing domain of HI is the application of intelligent algorithms in the clinical decision making, popularly known as ‘Artificial Intelligence in Medicine’ (AIM) [3]. Studies have revealed that intelligent algorithms are better suited in clinical medicine than traditional methods due to its ability to (i) handle uncertainty and (ii) gain maturity with time [4]. Thus, AIM research is mostly application-based in nature to examine the efficacies of these algorithms on clinical data, for example symptoms and signs [5]. Its key focus is to handle (i.e., capture, quantify, analyze, and model) subjective clinical symptoms for decision making, such as screening, diagnosis, and prognostic determination [6].

The Integration Of Fuzzy Logic System For Obstacle Avoidance Behaviour Of Mobile Robot

The Integration Of Fuzzy Logic System For Obstacle Avoidance Behaviour Of Mobile Robot

Mobile robot needs a robust controller to adapt the fast integration between the input and output due to the navigation in uncertain environment. Due to nonlinearity property of mobile robot, it is difficult to obtain absolute mathematical model of a system for designing its controller [8]. Amongst the various techniques available in this paradigm, Fuzzy Logic Controller offers a promising solution to handle the vague and imprecise information because Fuzzy based controller does not require mathematical model of the system [9].

Neuro Fuzzy System for Routing in a Computer Network

Neuro Fuzzy System for Routing in a Computer Network

Experts usually rely on common sense when they solve problems. They also use indistinct and indecisive terms. Then how can we represent expert knowledge that uses indistinct and unclear terms in a computer? The initiation of fuzzy logic gave the answer to this question. Fuzzy logic reflects how people think. It attempts to model our sense of words, our decision making and our common sense. Fuzzy logic as defined by [8] is determined as a set of mathematical principles for knowledge representation based on degrees of membership rather than on crisp membership of classical binary logic while Boolean or conventional logic uses sharp distinctions. It forces us to draw lines between members of a class and non-members. Based on the human brain, a neural network can be defined as a model of reasoning. The neural network collectively can be used to solve interesting and difficult problems because they made up of a highly connected network of individual computing elements (mimicking neurons); neural networks can generalize to solve diverse problems that have related features when trained [6]. One hybrid system that is the most evident today is neuro-fuzzy systems which apply a combination of artificial neural networks (ANN) and fuzzy systems [4]. ANN’s have been engaged in several applications ranging from disease diagnoses to rain forecasting. Their most noticeable feature is to learn from examples, and then adapt themselves based on actual solution

A NOVEL PREPROCESSING SYSTEM USING EVOLUTIONARY NEURO FUZZY SYSTEM

A NOVEL PREPROCESSING SYSTEM USING EVOLUTIONARY NEURO FUZZY SYSTEM

Neural networks and fuzzy systems are dynamical, parallel processing systems that approximation input-output functions [12]. Fuzzy logic is capable of modeling ambiguity, handling vagueness and supporting human-type reasoning. Whereas, neural-networks are capable of learning from scratch, without needing any a priori involvement provided that sufficient data are available or measurable. The neuro-fuzzy systems are the most prominent legislature of hybridizations in terms of the number of practical implementations. In NFS, the fuzzy inference system is the main subject of the hybridization; neural-network adds learning to an inference engine [5].

A GA-Based Adaptive Neuro-Fuzzy Controller for Greenhouse Climate Control System

In the first simulation, the outside weather conditions are T out = 35 C and w out = 4 g/kg (RH = 10%), while Si = 300 W/m 2 . The humidity ratio set point was raised from 18 to 24 g/kg (which corresponds to a relative humidity change from 60% to 80%) at t = 100 min, with the temperature set point 30 C; then the temperature set point was decreased from 30 to 28 C at t = 200 min (humidity ratio set point 24 g/kg), the responses for set point step changes in humidity ratio and temperature are in Fig. 4 . As we see the response under pro- posed G-ANFIS controller is very smooth and nearly close to set point than that given by ANFIS without tuning .The ventilation rate and water capacity of fog system as a control signals are shown in Fig. 5 . The simulation results clearly demonstrate the interacting control was attained and the closed-loop system response is very acceptable. Moreover, the response of the G-ANFIS controller is much faster than AFISN.

A Dynamical System Approach for Resource-Constrained Mobile Robotics

A Dynamical System Approach for Resource-Constrained Mobile Robotics

In the first technical contribution of the dissertation, we focus on a setup that considers a polygonal environment with holes and a simple robot equipped only with a clock and contact (or bump) sensors called a bouncing robot. We consider that the bouncing robot has access to a map of its environment, but is initially unaware of its position and orientation within that environment. This bouncing robot is modeled in a predictable way: the robot moves in a straight line and then bounces from the environment’s boundaries by rotating in place counterclockwise through a bouncing angle. The problem of global robot localization is how the robot deduces its pose (position and orientation) following its modeled behavior. Can this bouncing robot be globally localized without even knowing its initial pose? Different methods have been proposed to address this localization problem for robots with limited sensing [OL07, EKOL08, EL13]. In this contribution, we synthesize finite automata-based combinatorial filters for the global robot localization that take less computation time and memory compared to traditional Bayesian filter- based localization approaches [TFBD01, Fox03, LDW91].

Optimization of adaptive neuro fuzzy inference system based urban growth model

Optimization of adaptive neuro fuzzy inference system based urban growth model

Asselt’s categories for futures studies that more strongly emphasizes cognitive uncertainty is foresight which deals with multiple possible and plausible future (Veenman 2013). Foresight draws conclusions for the present and is therefore a broad range policy instrument that can serve various objectives (Cuhls 2000). In fact, Foresight is pre- sented in a scenario study as a rich detailed portrait of a plausible future world, or as future states of a system (Ber- rogi 1997). A scenario is not a forecast but a plausible description of what might occur (Enserink et al. 2010). In foresight studies, future images are given with two or more scenarios (Schwartz 1991; Goodwin and Wright 2010). It is uncertain which trends develop, continue or stop, and which unexpected events might happen, since multiple, alternative futures are possible in foresight analysis (Veen- man 2013). Normative, is the third category of future stud- ies of Asselt et  al. (2010). In contrast to forecasting and foresight studies, normative futures studies favor norma- tiveness instead of trying to be ‘neutral’ (Veenman 2013). The normative studies include two branches: backcast- ing and critical futures studies. Backcasting is concerned with how desirable futures can be created, rather than what futures are likely to occur. In backcasting, one envi- sions a desired future endpoint, and then works backward to determine what policy measures would be required to achieve such a future. Critical future studies emphasizes that images of possible futures are not neutral but repre- sent particular desires, values, cultural assumptions and world views (Asselt et al. 2010). Such future studies sketch a future that is considered ideal, for example, a situation of peace and tolerance, or a situation where the environ- mental burden is minimised. These types of future studies do not attempt to imagine one or more possible images of the future or one or more possible images of development without a statement being made about the desirability of it. According to Asselt’s category, this paper implemented the first category, forecasting.

A Neuro-Fuzzy controller based Wind Generation System using Flying Supercapacitors

A Neuro-Fuzzy controller based Wind Generation System using Flying Supercapacitors

ABSTRACT: This paper presents an approach of direct integration scheme for wind energy conversion systems using a capacitor-clamped three-level inverter-based supercapacitor. The main idea of this paper is to increase the capacitance of the clamping capacitors with the use of supercapacitors. The supercapacitor voltage is varied within a defined range. This variable voltage changes brings about many challenges. The uneven distribution of the space vector is the first challenge. To overcome this, space vector modulation technique is proposed. This generates undistorted currents even in the presence of dynamic changes in supercapacitor voltages. The harmonics are reduced by replacing conventional PI controllers with the Neuro-Fuzzy controllers which give better performance. The control strategies of the proposed system are discussed in detail. Simulation results are presented to study the efficacy of the proposed system in reducing wind power fluctuations.
