This document discusses the implementation of a matched filter-based direct sequence spread spectrum (DSSS) digital GPS receiver. It describes how a GPS receiver incorporates DSSS techniques to analyze signals from GPS satellites. Specifically, it designs a digital GPS signal receiver in VHDL for an FPGA system on chip application. The receiver takes digital GPS signals and performs C/A code demodulation, despreading, and outputs navigational data bits. It models communication subblocks like C/A code generator, BPSK demodulator, correlator, and threshold detector in VHDL and simulates them. The goal is to model a four channel receiver to process signals from four satellites mixed with additive white Gaussian noise.

Abstract Satellite GPS is undoubtedly the most popular and widely used three dimensional positioning technology in the world today, but despite this, cannot provide the positioning requirement in many every day requirements in different environments, such as urban and indoor due to the very weak signals from satellites. Even with high sensitivity GPS receiver cannot be given guaranteed in all situations and accuracies are typically of the order of tens to hundreds of meter at best. Accurate indoor positioning is required for a variety of commercial applications, including warehouse automation, asset tracking, emergency first-responders, and others. In fact, the general expectation of users today is for “GPS-like” positioning performance anywhere they go. Terrestrial GPS positioning is a new positioning technology, developed to address the failure of current satellite technologies for reliable ubiquitous (outdoor and indoor) positioning. In this paper key aspects of the new technology „terrestrial GPS positioning system‟ are discussed. Particular emphasis is given on the components like PseudoLite, PseudoNet, Rover (Moving terminal) and TimeLoc and their functionality. The technique and mathematical model used in terrestrial GPS positioning system is described in detail. The Results of installed Terrestrial GPS Positioning Systems are demonstrated and compared with Satellite GPS Positioning System. Index Terms: Indoor GPS system, PseudoLite, PseudoNet, TimeLoc
Data Collection via Synthetic Aperture Radiometry towards Global SystemIJERA Editor
Nowadays it is widely accepted that remote sensing is an efficient way of large data management philosophy. In
this paper, we present a future view of the big data collection by synthetic aperture radiometry as a passive
microwave remote sensing towards building a global monitoring system. Since the collected data may not have
any value, it is mandatory to analyses these data in order to get valuable and beneficial information with respect
to their base data. The collected data by synthetic aperture radiometry is one of the high resolution earth
observation, these data will be an intensive problems, Meanwhile, Synthetic Aperture Radar able to work in
several bands, X, C, S, L and P-band. The important role of synthetic aperture radiometry is how to collect data
from areas with inadequate network infrastructures where the ground network facilities were destroyed. The
future concern is to establish a new global data management system, which is supported by the groups of
international teams working to develop technology based on international regulations. There is no doubt that the
existing techniques are so limited to solve big data problems totally. There is a lot of work towards improving 2-
D and 3-D SAR to get better resolution.
A comprehensive insight towards pre-processing methodologies applied on GPS d...IJECEIAES
Reliability in the utilization of the Global Positioning System (GPS) data demands a higher degree of accuracy with respect to time and positional information required by the user. However, various extrinsic and intrinsic parameters disrupt the data transmission phenomenon from GPS satellite to GPS receiver which always questions the trustworthiness of such data. Therefore, this manuscript offers a comprehensive insight into the data preprocessing methodologies evolved and adopted by present-day researchers. The discussion is carried out with respect to standard methods of data cleaning as well as diversified existing research-based approaches. The review finds that irrespective of a good number of work carried out to address the problem of data cleaning, there are critical loopholes in almost all the existing studies. The paper extracts open end research problems as well as it also offers an evidential insight using use-cases where it is found that still there is a critical need to investigate data cleaning methods.

Electrically small antennas: The art of miniaturizationEditor IJARCET
We are living in the technological era, were we preferred to have the portable devices rather than unmovable devices. We are isolating our self rom the wires and we are becoming the habitual of wireless world what makes the device portable? I guess physical dimensions (mechanical) of that particular device, but along with this the electrical dimension is of the device is also of great importance. Reducing the physical dimension of the antenna would result in the small antenna but not electrically small antenna. We have different definition for the electrically small antenna but the one which is most appropriate is, where k is the wave number and is equal to and a is the radius of the imaginary sphere circumscribing the maximum dimension of the antenna. As the present day electronic devices progress to diminish in size, technocrats have become increasingly concentrated on electrically small antenna (ESA) designs to reduce the size of the antenna in the overall electronics system. Researchers in many fields, including RF and Microwave, biomedical technology and national intelligence, can benefit from electrically small antennas as long as the performance of the designed ESA meets the system requirement.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
