&home_txt1=Welcome to Dr Petros Lalos's Personal Page!
&home_txt2=Innovation
The term innovation derives from the Latin innovatio, the noun of action from innovare. I strive to see things differently, and focus on quickly sizing up problems and develop creative solutions to them.
&home_txt3=About Me
&home_txt4=Here are some facts about me...
I was born in Thessalonica of Greece. I grew up in different Cities in Greece and
Germany
(where I spend my elementary School years), as both my parents were
elementary School-teachers and therefore transferred on a regular base.
I consider myself prerogatived, as in his early years he came to appreciate
different cultures and ways of living.

&home_readmore_title1=About Me
&home_readmore_txt1=After finishing High School in Thessalonica, I studied Physics at the Aristotelian University of Greece from where I received his first degree (Ptyhio). I served as a telecommunications expert in the Greek Army and was discharged in 1996. Afterwards I started working (among other jobs) as a physics Professor in Greek preparatory High Schools and later on as an IT Professor in Greek Universities, British Universities (their Greek franchised Branches), Technological Institutes and public and private Training Institutes (IEK).
I obtained my MSc in Information Technology from Paisley University of Scotland (Thesis topic: 'ADETO - A web-based adaptive educational tool'). I obtained my PhD from the Dept of Electronics, Computers Telecommunications and Control - Faculty of Physics, University of Athens in the field of Mobile Location based Services.
Family
I have an older brother, Lefteris who is divorced and has two children.

&products_readmore_txt1=This paper describes a proposition for the improvement of global cities traffic problem with the combined use of XPS technologies (Hybrid positioning systems) and Web technologies.
A car-pool is the concept of people sharing a vehicle for a ride when their departure and destination locations are similar.
A Taxi pool is a mode of transport that falls between private transport and conventional bus transport. The routes are fixed or semi-fixed, but with the added convenience of stopping anywhere to pick or drop passengers and not having fixed time schedules.
Dynamic car pool is the dynamic coordination of ride offerings and ride requests based on the, in real time created, transportation and offering needs.
Hybrid Positioning Systems - XPS are systems for finding the location of a mobile device (like PDA, SmartPhone, cellular, etc) using various positioning technologies.
This work explains how XPS technologies combined with web technologies can be utilized in order to support a dynamic network of car and taxi pool services that will maximize the exploitation of empty seats traveling with tenable advantages.&
&products_readmore_txt2=High-resolution images are used today in many scientific and business areas like culture, astronomy, engineering, architecture, publishing, and e-commerce. For example, many civil structures need periodic examination for proper operation and/or for maximizing life span. For structural safety monitoring, a critical element is structural damage diagnosis using high quality images. Fu and Moosa presented a new approach to diagnosing structural damage using high-resolution images, which can be provided by a charge coupled device (CCD) or CCD camera. In addition, high-resolution images can be used in the process of land use dynamic monitoring and object recognition and in other application domains.
The advance of pictorial databases and collections of high-resolution images makes it interesting to consider image-browsing tools. From another perspective, the need to easily and quickly view image data over the Internet has motivated researchers to develop various image transmission schemes designed to reduce image file sizes and maximize the speed at which an observer views remotely-located images.
In general, Internet users view high-resolution images using various Web applications. One problem arising in this case is that clients have to download a large amount of information for high quality images, usually through limited bandwidth connections. This process is time-consuming. This problem is even more noticeable in case a user wants to navigate in high quality image collections. The network load presents a major bandwidth and server availability issue for the publisher of the digital content, as it maximizes the effort of all the involved network resources of the publisher's infrastructure.
Viewing digital content in devices with screen analysis lower than the analysis of the image can cause display problems. For example, viewing high resolution images in notebooks or PALMs can be a tedious and eventually an unsuccessful action. In general users must be able to view the content with handheld devices like personal digital assistants (PDAs) and smartphones without having to compromise the offered features.
To solve the above problems a generic zoomable image browser was created, taking the previous considerations into account. This browser displays detailed multimedia content like images, or other digital material that could be transformed to images (e.g. PDF files), in an interactive, manageable and user-friendly way, with minimum network and server demands. Users can zoom into specific areas of the images to see high resolution illustrations of these parts. The browser is developed using lightweight and widespread technologies to be platform independent. Another feature of the browser is the placement of annotations on the portrayed content to support collaboration between viewers of the digital content.
This paper presents this zoomable browser for high quality images and discusses its novel features as well as its differences from other image browsers.&

&prices_txt1=Location Based Services
&prices_txt2=LBS
A Location Based Service
(LBS) is an information or entertainment service, acces-
sible with mobile devices
through the mobile network.
LBS can be used in a variety of contexts, such as health, work, personal life, etc. [5]. LBS include services to identify a location of a person or object, such as discovering the nearest banking cash machine or the whereabouts of a friend or employee. LBS include parcel tracking and vehicle tracking services. LBS can include mobile commerce when taking the form of coupons or advertising directed at customers based on their current location. They include personalized weather services and even location-based games.

&prices_txt4=E-Learning and M-Learning
&prices_txt5=E-learning
E-learning comprises all forms of electronically supported learning and teaching. The information and communication systems, whether networked or not, serve as specific media to implement the learning process. E-learning is essentially the computer and network-enabled transfer of skills and knowledge.
E-learning applications
E-learning applications and processes include Web-based learning, computer-based learning, virtual classroom opportunities and digital collaboration. Content is delivered via the Internet, intranet/extranet, audio or video tape, satellite TV, and CD-ROM. It can be self-paced or instructor-led and includes media in the form of text, image, animation, streaming video and audio.
M-Learning
The term M-Learning, or "mobile learning", is any sort of learning that happens when the learner is not at a fixed, predetermined location, or learning that happens when the learner takes advantage of the learning opportunities offered by mobile technologies. In other words mobile learning decreases limitation of learning location with the mobility of general portable devices.
M-Learning applications
Learning with portable technologies including but not limited to handheld computers, MP3 players, notebooks and mobile phones. M-learning focuses on the mobility of the learner, interacting with portable technologies, and learning that reflects a focus on how society and its institutions can accommodate and support an increasingly mobile population.
M-Learning advandages
M-Learning is collaborative and brings strong portability by replacing books and notes with small RAMs, filled with tailored learning contents. In addition, it is simple to utilize mobile learning for a more effective and entertaining experience.&

This concept of location based systems is not compliant with the standardized concept of real-time locating systems and related local services (RTLS), as noted in ISO/IEC 19762-5 and ISO/IEC 24730-1. Some examples of location-based services are:
