Technical Review of Residential Programmable Communicating Thermostat Implementation for Title 24-2008
Software, objects and home space (NIRSA) Working Paper Series. No. 35
Through a series of interrelated developments, software is imbuing everyday objects with
capacities that allow them to do additional and new types of work. On the one hand,
objects are remade and recast through interconnecting circuits of software that makes
them machine-readable. On the other, objects are gaining calculative capacities and
awareness of their environment that allow them to conduct their own work, with only
intermittent human oversight, as part of diverse actant-networks. In the first part of the
paper we examine the relationship between objects and software in detail, constructing a
taxonomy of new types of coded objects. In the second part we explore how the
technicity of coded objects is mobilised to transduce space by considering the various
ways in which coded objects are reshaping home life in different domestic spaces

U.S. Telecommunications Today, April 1999
This short essay examines the current conditions in the US telecommunications sector (April 1999). We examine the impact of technological and regulatory change on market structure and business strategy. Among others, we examine the impact on pricing of digitization and the emergence of internet telephony. We briefly examine the impact of the 1996 Telecommunications Act on market structure and strategy in conjunction with the history of regulation and antitrust intervention in the telecommunications sector. After discussing the impact of wireless technologies, we conclude by venturing into some short term predictions. We express concern about the derailment of the implementation of the 1996 Act by the aggressive legal tactics of the entrenched monopolists (the local exchange carriers), and we point to the real danger that the intent of Congress in passing the 1996 Act to promote competition in telecommunications will not be realized. After discussing the impact of wireless technologies, we comment on the wave of mergers in the Telecommunications and cable industries.

Middleware Technologies for Cloud of Things - a survey
The next wave of communication and applications rely on the new services
provided by Internet of Things which is becoming an important aspect in human
and machines future. The IoT services are a key solution for providing smart
environments in homes, buildings and cities. In the era of a massive number of
connected things and objects with a high grow rate, several challenges have
been raised such as management, aggregation and storage for big produced data.
In order to tackle some of these issues, cloud computing emerged to IoT as
Cloud of Things (CoT) which provides virtually unlimited cloud services to
enhance the large scale IoT platforms. There are several factors to be
considered in design and implementation of a CoT platform. One of the most
important and challenging problems is the heterogeneity of different objects.
This problem can be addressed by deploying suitable "Middleware". Middleware
sits between things and applications that make a reliable platform for
communication among things with different interfaces, operating systems, and
architectures. The main aim of this paper is to study the middleware
technologies for CoT. Toward this end, we first present the main features and
characteristics of middlewares. Next we study different architecture styles and
service domains. Then we presents several middlewares that are suitable for CoT
based platforms and lastly a list of current challenges and issues in design of
CoT based middlewares is discussed.Comment: http://www.sciencedirect.com/science/article/pii/S2352864817301268,

Rover-II: A Context-Aware Middleware for Pervasive Computing Environment
It is well recognized that context plays a significant role in all human endeavors. All decisions are based on information which has to be interpreted in context. By making information systems context-aware we can have systems that significantly enhance human capabilities to make critical decisions.
A major challenge of context-aware systems is to balance usability with generality and extensibility. The relevant context changes depending on the particular application. The model used to represent the context and its relationship to entities must be general
enough to allow additions of context categories without redesign while remaining usable across many applications. Also, while efforts are put in by application designers and developers to make applications context-aware, these efforts are customized to specific
needs of the target application, and only certain common contexts like location and time are taken into account. Therefore, a general framework is called for that can (i) efficiently maintain, represent and integrate contextual information, (ii) act as an integration platform
where different applications can share contexts and (iii) provide relevant services to make efficient use of the contextual information. This dissertation presents:
* a generic and effective context model - Rover Context Model (RoCoM) that is structured around four primitives: entities, events, relationships, and activities; and practically usable through the concept of templates,
* a flexible, extensible and generic ontology - Rover Context Model Ontology (RoCoMO) supporting the model, that addresses the shortcomings of existing ontologies,
* an effective mechanism of modeling the context of a situation, through the concept of relevant context, with the help of situation graph, efficiently handling and making best use of context information,
* a context middleware - Rover-II, which serves as a framework for contextual information integration, that could be used not just to store and compile the contextual information, but also integrate relevant services to enhance the context information; and more importantly, enable sharing of context among the applications subscribed
to it,
* the initial design and implementation of a distributed architecture for Rover-II, following a P2P arrangement inspired from Tapestry,
The above concepts are illustrated through M-Urgency, a context-aware public safety system that has been deployed at the University of Maryland Police Department
