WSN has important applications such as habitat monitoring, structural health monitoring, target tracking in military and many more. This has evolved due to availability of sensors that are cheaper and intelligent but these are having battery support. So, one of the major issues in WSN is maximization of network life. Heterogeneous WSNs have the potential to improve network lifetime and also provide higher quality networking and system services than the homogeneous WSN. Routing is the main concern of energy consumption in WSN. Previous research shows that performance of the network can be impro…
Router Assisted Congestion Control (RACC) was designed to improve endto- end congestion control performance by using prior knowledge on network condition. However, the traditional Internet does not provide such information, which makes this approach is not feasible to deliver. Our paper addresses this network information deficiency issue by proposing a new congestion control method that works on the Software Defined Network (SDN) framework. We call this proposed method as PACEC (Path Associativity Centralized Congestion Control). In SDN, global view of the network information contains the netw…
This paper presents and implements a Super-Twisting high order sliding mode control for a BLDC motor. Conventional sliding mode controller has a very fast response, it allows the convergence in finite time and characterized by its robustness against disturbances and uncertainties; However, the chattering phenomenon due to the discontinuous nature of its control organ degrades its performance, especially in case of mechanical membranes control. To overcome this disadvantage, the most commun solutions are based on the adaptation of its discontinuous nature at static regime, it reduces effectivel…
This paper presents a review of wind speed estimation based on Kalman filter technique applied to wind turbine systems. Generally, wind speed measurement is performed by anemometer. The wind speed provided by the anemometer is measured at a single point of the rotor plane which is not the accurate wind speed. Also, using anemometer increases the system cost, maintenance, complexity and reduces the reliability. For these reasons, estimation of wind speed is needed for wind turbine systems. In this paper, the several wind speed estimation methods based on Kalman filter method used for wind turbi…
Access to huge data is needed for an appropriate structure and grouping of data such that the access to the data becomes easier, the status which clustering algorithms are doing this for us. However, special attentions are paid in recent years on semantic data clustering which in semantic interpretation of the input data is needed. In this paper, three modified clustering methods are used and the results of these techniques are evaluated. Based on this, first a technique is developed in which some rules are applied to prevent confusion within clusters. A rule-based clustering can be applied to…
This paper reports the finding a new chaotic system with a pear-shaped equilibrium curve and makes a valuable addition to existing chaotic systems with infinite equilibrium points in the literature. The new chaotic system has a total of five nonlinearities. Lyapunov exponents of the new chaotic system are studied for verifying chaos properties and phase portraits of the new system are unveiled. An electronic circuit simulation of the new chaotic system with pear-shaped equilibrium curve is shown using Multisim to check the model feasibility.
Interferometric Fiber Optic Gyroscope (IFOG) has to operate in closed loop condition to achieve inertial grade performance. The closed loop system is mainly depends upon the amplitude of the ramp signal (V2Ï€ of IOC) and bias (square wave) signal frequency (fbias). The digital phase ramp function is given as feedback to the optical system and makes gyro to null condition. The peak-to-peak amplitude (VÏ€/2) of biasing signal is one-fourth of the ramp amplitude (V2Ï€). If there are any variations in the amplitude of the ramp and biasing signals, then it introduces variations in the gyro…
Interiority, in relation to my practice, is the inherent curiosity to the notions of process, time and duration. It is a practice of mark making, marking time, making time, and time making; foregrounding duration and marking an occurrence. My technique is one of working responsively to interiors, allowing particular temporal conditions to surface within specific sites and situations. The marks – whether they be on a canvas, a house, a building, or within a gallery – materialise immateriality and allow the residue of particular processes to be assembled as collections of materialised and sp…
Museum dioramas are widely recognised as historic visual tropes used to frame the grandeur of the outside world within an interior viewing space. With the development of digital technologies, data projection and soundscape have increasingly replaced diorama production as a means to transform these once static-animal-posed-in-painted- habitat with immersive interiors that engage the visual and aural senses alike. Andre Breton proposes that two modes of consciousness exist: an exterior world of facts and an interior world of emotions. These interiors and exteriors produce an interface and exchan…
This paper investigates the concept of ‘passage territories’ (Sennett, 2006), as living spaces constructed from one’s passage of movement from one separate space to another, and how it extends the discussion of interiority in contested contexts. Through observations of living spaces and the narrative accounts of dwellers’ in Kampung Pulo and Manggarai neighbourhoods of Jakarta, this study draws attention to the interiority of dispersed and layered spaces occupied by the kampungs’ dwellers. In this context, passage territories are driven by a) a limitation of space that, in turn, trig…
Understanding the relations between human being and its environment is critical in our attempt to create an appropriate built environment. Interior as a discipline has a privilege to be in the intersection between subjective experience of human users and the physical manifestation of environment occupied by the human. Looking at interiority as a relational construct that occurs between the users and environment should be an essential basis for design practice. This issue of Interiority intends to explore various forms of relational construct that emerge in the interaction between space and the…
Surface articulation is a critical issue for interior architecture, and this paper sees the wall as a point of intersection where art and structure may converge and collide. A place of experimentation and a site of performance, built volumes and surface embellishments blur and reinforce edge conditions and ornament as embellishment and essential structure merge. This paper explores a sculptural relief Copper Crystals (1965) constructed by Jim Allen for the ICI (Imperial Chemical Industries) House (1964) situated at 61 Molesworth Street in Wellington, New Zealand. Following the building's failu…
Our sense of place in the world is mediated through our everyday interactions with both people and space (Seamon, 1985). Everydayness is one of the most profound levels and shapers of human experience, yet too often this level of relation is overlooked and taken for granted in the design of environments (Dyck, 2005; Tuan, 1977). In this article, I present a first-person phenomenological account of my everyday interactions with doors on a university campus to uncover contested notions of interiority. My body-space routines reveal how a sense of outsideness/insideness is controlled through my in…
This article discusses Icelandic installation artist Olafur Eliasson’s approach of the threshold as a productive liminal space rather than as a static boundary between the inside and the outside. Often defined as the physical division between the interior and the exterior in architecture, the authors argue that by looking at Eliasson’s works in detail, the threshold’s inherent capacity of comprising a dynamic dialogue between inside and outside where one is determined by the other unfolds. This paper proposes that designing the relationships between inside and outside involves subtle ren…
This architectural historical study aims to interrogate rituals of contemporary inhabitation in the United Kingdom by tracing the rise of the self storage facility. While the proliferation of domestic self storage in the UK is derived from a web of correlations, this research considers self storage as a lens through which the subjective experience of inhabiting the neoliberal city, may be understood. Drawing from archaeological methods to conduct a material study of the contents of abandoned storage units, this study engages specifically with self storage as a long-term solution to domestic st…
‘Performative’ is an emerging term in architectural discourse. The word ‘performative’ is able to describe spatial qualities and design approaches. The term is mostly linked to the concepts of open-form, and flexibility which are characters that give the spatial design a strategic aspect as the ability to anticipate and host predicted and unpredicted occurrences, and to adjust to future changes, which also gives architecture the character of an unfolding ‘event’ in time and in space. This paper seeks to investigate the terminological and the theoretical dimensions of the term ‘pe…
Much like Walter Benjamin's analysis of the Parisian arcades during the interwar years of the early 20th century, emerging methods of seeing interior spaces reveal a deeper gaze into the contextual, material, and phenomenological conditions that produce more nuanced visions of interiority. A collective consciousness surrounding these constructed narratives is reflected in charged associations with the most salient imperatives of our time—globalisation, resource depletion, ecological degradation, and political instability—as well as their corresponding effects on the built environment. …
