Computer forensics is a key science and competency in meeting the growing risks of cybercrime, as well as for criminal investigation generally. In order to provide irrefutable evidence of a potential crime, a specialist in the incident response team (e.g. an IT forensics specialist) must secure the digital evidence in accordance with the correct procedure. There are no strict guidelines on how to do this. It is known that the authenticity and fidelity of data must be preserved. This article will collect good practices developed by specialists in the field of computer forensics. The process of securing the evidence material from a digital data sources for later analysis will be presented.

Introduction/background: The aim of the article is to check whether the holistic approach in the case of high-tech industries is the optimal solution in the field of M&A process analysis. Aim of the paper: Two research hypotheses were formulated: H1 – It is impossible to create an effective universal holistic model for even a single high-tech industry. H2 – The key element of the process of assessing the validity of M&A processes is the potential use value of the acquired knowledge and/or technology. Materials and methods: A quantitative analysis of articles relating to holistic models and sources relating to the specificity of specific market M&A processes were used. Results and conclusions: The results obtained revealed that the analysis of selected mergers and acquisitions allowed it to be stated that the key aspect determining the success or failure of the M&A process is the value of the acquired knowledge and technology and its applicability within the newly created organisational structures. It was also found that holistic models, apart from being cost-intensive and time-consuming, are also characterised by a lack of standardisation of the model and the lack of assessment at both the level of one industry and within a single branch of the economy. Thus, the creation and application of universal holistic models in high-tech industries may turn out to be ineffective and lead to decision errors at the level of the company's development strategy.

In this paper, we analyze the acquisition and tracking performance of signal using a tiered differential polyphase code as the secondary code. The Zadoff-Chu sequence is known to have a CAZAC (Constant Amplitude Zero Auto-Correlation) characteristics. The secondary code generated by differential encoding of the Zadoff-Chu sequence also has the same characteristics as the Zadoff-Chu sequence. Therefore, long integration will give better correlation results. We compare signal acquisition and tracking performance when using the NH sequence and Zadoff-Chu sequence as the secondary code. Monte-carlo simulation is performed using MATLAB. We use the probability of detection and the mean acquisition time for signal acquisition performance and tracking jitter for signal tracking performance.

The acquisition parameters and methodology of seismic data processing for high-resolution seismic imaging viewed through relative amplitude preservation are presented. An example of the obtaining of high-quality, shallow seismic data with a variable end-on spread is shown. The source used for the project is an accelerated weight drop. The study area lies within the mine waste disposal area, near Rudna village (Fore-Sudetic Monocline, WS Poland), and results are given for a 2D experimental profile. The aim of the project was to design optimal acquisition and processing parameters for the detailed recognition of Tertiary deposits. The proposed acquisition parameters are a compromise between time, cost and results. High-resolution seismic imaging enables the determining of layers within the range of thicknesses between 5 and 15 m, while the maximal depth of imaging reaches 400 m.

The development of enterprises in the globalised world depends on their development potential and ability to compete with other entities. Of key importance in the field of competitiveness is access to innovative technologies providing a competitive advantage and the ability to cooperate in their acquisition with other entities, e.g. in clusters. The authors attempted to identify the sources of technology and financing options used by companies in the metal processing industry. The studied entities are part of a cluster of national importance, and the adopted research method is based on an interview questionnaire. Studies have shown that most companies buy ready-made solutions and to a lesser extent cooperate in acquiring technology. Noticeable is also a relatively large share of financing investments in new technologies from public funds.

Several methods of acquisition have been developed so far which aim at accelerating the acquisition process and detection of weak GPS signals. In many of these the search is parallelized in code or frequency space. However, sometimes the number of samples in code periods based on sampling frequency is not equal to required number of Radix-2 FFT algorithm. So it is again computing the DFT normal method without FFT. The main purpose and objective of this project is to implement a fast and robust for weak signal acquisition algorithm “Double Block Zero Padding Acquisition” (DBZP) for GPS L1 civilian signal. Technique is developed even for the signals where number of samples in the code period taken for correlation is not satisfying the required number for Radix-2 algorithm. It is also suitable for weak GPS signals acquisition, which require Pre-detection, or integration (correlation) Time (PIT) to be long.

In 2010 a collaborative working group was formed under the professional associations: International Association of Geodesy (IAG WG4.2.5) and International Federation of Surveys (FIG WG5.5). Entitled ubiquitous positioning, this working group aims to harness and develop existing research outputs available internationally in this research domain. Our goal over the next four years is to provide an online resource for academic and industry professionals, who can use these research outputs thereby reducing duplication and facilitating more rapid progress in the development of ubiquitous positioning systems. This paper presents a summary of the research activities and results of the working group to date. In particular, it presents the results of extensive testing to characterize the performance of a range of low-cost MEMS inertial sensors. The test scenarios, data acquisition software, processing tools and results obtained will be fully described and presented. The performance of these sensors in augmenting GNSS positioning is also presented using results obtained from a combination of loosely and tightly coupled Kalman filters. Finally, the future plans for the working group over the next four years and opportunities for wider collaboration will be discussed.
