Introduction to Monte-Carlo

The idea of Monte Carlo methods is this—generate some random samples for some random variable of interest, then use these samples to compute values you’re interested in.

On Mobile Wireless Tags

Namiot D., Sneps-Sneppe M. On mobile wireless tags // Automatic Control and Computer Sciences. — 2015. — Vol. 49, no. 3. — P. 159–166.

The subject of the article refers to services of mobile networks related to a context. We are examining the questions of the development of mobile services employing wireless tags. In addition to this, a new model of usage (application) of Core Bluetooth devices is offered. In our model Bluetooth devices act as tags and are used for reference (binding) and the subsequent context-dependent determination of data available to mobile users. Mobile phones, as well as already existing devices with Bluetooth support, can be used as such dynamic tags. In this case a single mobile application is sufficient for coverage of all stages of the life cycle of contextual services. The application provides a presentation of a tag (tags) and the binding of informational content to these tags, as well as the viewing of data bound to other tags. The possible application fields are applications for retail and service organizations and context-dependent services for Smart Cities. DOI

Memory leaks in JavaScript

Our new paper: Evgeniy Ilyushin, Dmitry Namiot "On JavaScript Memory Leaks". International Journal of Open Information Technologies 3.7 (2015): 27-31.

As soon as more and more the modern applications are deployed on the web, JavaScript has become a mainstream programming environment. JavaScript applications nowadays are big programming systems. We can mention here web portals, online games, graphics, media management, and even data science. Of course, the memory management is a very important problem, especially, for the dynamic programming languages. In this paper, we provide a survey of memory leaks patterns in JavaScript.

Network Proximity in Web Applications

Our new paper: Dmitry Namiot, Manfred Sneps-Sneppe "On Network Proximity in Web Applications"

In this paper, we discuss one approach for development and deployment of web sites (web pages) devoted to the description of objects (events) with a precisely delineated geographic scope. This article describes the usage of context-aware programming models for web development. In our paper, we propose mechanisms to create mobile web applications which content links to some predefined geographic area. The accuracy of such a binding allows us to distinguish individual areas within the same indoor space. Target areas for such development are applications for Smart Cities and retail.

Data Science Books

27 free Data Mining books

We would like one more: Statistics Done Wrong is a guide to the most popular statistical errors and slip-ups committed by scientists every day, in the lab and in peer-reviewed journals. Many of the errors are prevalent in vast swaths of the published literature, casting doubt on the findings of thousands of papers. Statistics Done Wrong assumes no prior knowledge of statistics, so you can read it before your first statistics course or after thirty years of scientific practice.

Geo-location for Telecom Operators

Our new paper: Dmitry Namiot, Manfred Sneps-Sneppe "On Geo Location Services for Telecom Operators"

This paper presents location based service for telecom providers. Most of the location-based services in the mobile networks are introduced and deployed by Internet companies. It leaves for telecom just the role of the data channel. Telecom providers should use their competitive advantages and offer own solutions. In this paper, we discuss the sharing location information via geo-messages. Geo messages let mobile users share location information as signatures to the standard messages (e.g., email, SMS). Rather than let some service constantly monitor (poll) the user location (as the most standalone services do) or share location info within any social circle (social network check-in, etc.) The Geo Messages approach lets users share location data on the peer to peer basis. Users can share own location info with any existing messaging systems. And messaging (e.g., SMS) is the traditional service for telecom.
