Software based encoder/decoder generation for data exchange optimization in the internet of things : master's thesis
Tjaž Vračko, 2022, magistrsko delo

Opis: Efficient encoding of data is an important part of projects in the Internet of Things space. Communication packets must be kept as small as possible in order to minimize the power consumption of devices. In this thesis, an automatic code generation tool, irpack, is proposed that will unify the way packets are defined across all future projects at Institute IRNAS. Using a schema, this tool generates source code of encoders and decoders in target programming languages. A schema evolution system is also defined, by which changes to packets can be compatible across multiple versions. The tool is then applied to a selection of past projects to gauge its usefulness. It is determined that irpack is able to encode the same data into a similar or smaller size packet, while also providing additional versioning information.

Modeling of molecular and cellular mechanisms involved in [Ca sup 2+] signal encoding in airway myocytes
Marko Marhl, Denis Noble, Etienne Roux, 2006, pregledni znanstveni članek

Opis: In airway myocytes signal transduction via cytosolic calcium plays an important role. In relation with experimental results we review models of basic molecular and cellular mechanisms involved in the signal transduction from the myocyte stimulation to the activation of the contractile apparatus. We concentrate on mechanisms for encoding of input signals into Ca2+ signals and the mechanisms for their decoding. The mechanisms are arranged into a general scheme of cellular signaling, the so-called bow-tie architecture of signaling, in which calcium plays the role of a common media for cellular signals and links the encoding and decoding part. The encoding of calcium signals in airway myocytes is better known and is presented in more detail. Inparticular, we focus on three recent models taking into account the intracellular calcium handling and ion fluxes through the plasma membrane. Themodel of membrane conductances was originally proposed for predicting membrane depolarization and voltage-dependent Ca2+ influx triggered by initialcytosolic Ca2+ increase as observed on cholinergic stimulation. Cellular models of intracellular Ca2+ handling were developed to investigate the role of a mixed population of InsP3 receptor isoforms and the cellular environment in the occurrence of Ca2+ oscillations, and the respective role ofthe sarcoplasmic reticulum, mitochondria, and cytosolic Ca2+-binding proteins in cytosolic Ca2+ clearance. Modeling the mechanisms responsible for the decoding of calcium signals is developed in a lesser extent; however, the most recent theoretical studies are briefly presented in relation with the known experimental results.
