We present an improved Locality-Sensitive Hashing for similarity search under high dimension search. Our scheme improves the running time based on the earlier algorithm Locality-Sensitive Hashing for hamming distance and euclidean distance. In this paper we have collected a database of The MNIST DATABASE, we proposed nearest neighbor search in the database and can get a good result in an acceptable time. The experimental results show that our data structure is up to about 10 times faster than ordinary Locality-Sensitive Hashing when working on a database of 60000 samples. At the same time, the accuracy rate and recall rate are higher than earlier algorithms.

This paper introduces a PSpice model for adjustable voltage regulator. The model for AP2204 consist of power transistor, voltage reference, line regulation and load regulation and so on. The model was tested in three cases: 1) change the feedback resistance; 2) change the input voltage; 3) change the load resistance. The results show that the model is correct.

The aim of this project is to build a wireless endoscopic system based on the Wi-Fi technology, in case to make this medical equipment available in much more circumstances. The core idea is to cope with the problem that the traditional endoscopic used before is inconvenient since there must be a dedicated receiver which is made on purpose. With the popularity of mobile intelligent terminal, the Wi-Fi based wireless transmission technology could make it easy to use the common Android mobile phone or iPad as the endoscopic receiver. In this project, we take CC3200 as the MCU of endoscopic system which integrates the Wi-Fi module in one chip.

Automatic marking technology for the objective questions in paperless marking has performed very well now. However, there are rarely studies on the automatic marking technology for subjective items, which are still reviewed by hand. This paper proposed an algorithm based on segment gray histogram. It divided the image of an examination question into four areas, and then calculated gray histogram of four segments simultaneously using parallel computation. As shown by experimental results, correct recognition rate is over 92% and the recognition speed is 92.73 seconds per 1,000 questions, which will meet recognition accuracy and real-time requirements in automatic paperless marking.

This paper presents the results of a research on implementation of online tests in e-course and the effort of their improvement in order to design the basis for formative and summative students' assessment. The research was conducted on Information Systems course at the Department of Informatics, University of Rijeka, and it included 335 students. After the first phase of transition from traditional paper-based tests to online tests, in the second phase an important improvement of question bank and online tests structure was performed. Special attention was paid to formative self-assessment by using online tests. The results of a survey that collected students' attitudes regarding self-assessment online tests are also presented.

The paper deals with the advanced detection and diagnostics of physical hardware modules of remote laboratories based on the Internet School Experimental System (ISES) platform. Interested students can use the ISES remote laboratory for experimenting as a unique educational tool to understand the desired phenomena. This is particularly useful for distant students, whom are often not enabled frequent experimental and laboratory courses. The main reason to deal with this issue is the absence of any detection technique of faults and any diagnostic system to help improving the administration. The diagnostic system is designed for those responsible for the ISES remote laboratory hardware functioning. The first chapter, the state of the art, aims to introduce the ISES remote laboratory concept. The next chapter presents the Runtime modules detection component used for the identifying and detecting connected ISES hardware modules by using two bit triplets and masks. The second part of this chapter describes the Rule-based methods exploiting heuristics to detect faults in these modules. The final chapter summarizes all the benefits brought for involved administrators of the ISES remote laboratories.

We have developed and use in our Department the Artificial Intelligence Teaching System (AITS). AITS is an adaptive and intelligent tutoring system that teaches AI aspects and uses AI techniques for personalized learning and assessment of the students. In this paper, we present the way that AITS can help students in learning search algorithms and the learning approaches and activities it offers. Also, we present a tool developed to assist tutors to create exercises in a semi-automatic way. It is an assistant tool to be embedded into the AITS system that produces different types of interactive exercises related to AI search algorithms. The tool takes as input a number of parameters regarding the desired exercise and it creates semi-automatically the interactive exercise based on the corresponding parameters. The tool aims at helping tutors in creating and updating the teaching material. Results gathered from an evaluation study are quite promising.
