In this work we compare channel estimation algorithms for use in an iterative CDMA receiver in a block fading environment. The receiver consists of a soft multiuser data estimator, a bank of single user decoders, and a multiuser channel estimator. The multiuser data estimator is implemented as parallel interference canceler with unconditional post-MMSE filtering (PIC-MMSE) and the decoder is a sof

The paper describes a novel method for self tuning cylinder pressure based heat release computation that is suitable for online usage in e.g. combustion phasing control applications. The method estimates the polytropic exponents and cylinder pressure offsets immediately preceding and succeeding the combustion event respectively using a fast nonlinear least squares method. The polytropic exponent a

User attitudes on privacy with respect to location data has been extensively studied. However, user attitudes of privacy in relation to proximity sensing is still lacking. We present the results from a survey conducted on users of a proximity sensing application we developed and diffused by handing out phones with the proximity sensing application pre-installed, with 31 respondents. The results co

Control is traditionally applied using periodic sensing and actuation. In some applications, it is beneficial to use instead event based control, to communicate or make a change only when necessary. There are no known general closed form solutions to such event based control problems. We consider stationary event-based control problems with mixed continuous/discrete time dynamics and stochastic di

Implementation aspects of self-tuning regulators are discussed in the paper. There is a large discrepancy between simulation or academic algorithms and practical algorithms. In the idealized environment of simulations it is easy to get different types of adaptive algorithms to perform well. In practice the situation is quite opposite. The adaptive or self-tuning controller must be able to handle n

We study here deterministic broadcasting in geometric radio networks (GRN) whose nodes have complete knowledge of the network. Nodes of a GRN are deployed in the Euclidean plane (R 2) and each of them can transmit within some range r assigned to it. We adopt model in which ranges of nodes are non-uniform and they are drawn from the predefined interval 0 ≤ r min ≤ r max . All our results are in the

To find a controller that provides the maximal stability margin to an LTI system under rank-one perturbations is a quasiconvex problem. In the paper, the dual quasiconvex problem is obtained, using the convex duality arguments in the Hardy space H∞. It is shown that the dual problem can be viewed as minimization of a "length" of uncertainties that destabilize the system. Several examples establish

The climate conditions inside nuclear reactor containments depend on several parameters e.g. different moisture and heat sources; the containment design; material properties etc. Knowledge about the climatic condition is an important area to e.g. maintain a proper condition for mechanical and electrical equipment; minimize the corrosion risks of reinforcement and metallic components; prevent vapor

This paper describes an 8-Bit, 100-MHz current steering CMOS low glitch interpolation digital to analog converter (DAC). It includes a 16-tap voltage controlled delay line and 8-Bit based linear interpolators, making the effective clock rate up to 1.6-GHz. With the linear interpolation, the requirement on the analog reconstruction filter is relaxed, and low glitch digital to analog conversion is a

This paper discusses the relation between logistics and Mergers and Acquisitions (M&A) of companies within the same industry and same industry level (i.e. horizontal M&A). The purpose is to study the effects of M&A on the logistics resources of companies and the possibility for companies to benefit from the re-organising of these resources in the form of synergies. The study hopes to a
