5. FORENSIC DIAGNOSIS

Forensic diagnostics - recognition, identification, determination of signs to establish the properties and state of objects, dynamics and circumstances of events, causes and relationships of phenomena and facts associated with a crime event.

The task of forensic diagnostics is the establishment (definition, disclosure) of objective truth by studying and explaining the properties and states of an object (phenomenon).

The methodological basis of the process of such knowledge is the theory of reflection.

Forensic diagnostics is based on the general laws of knowledge, introduces modern methods of mathematical and many other types of analysis. The results of diagnostics are a kind of obtained factual data necessary for the thought processes of proving.

Diagnostic research conducted in all areas of forensic technology.

objects forensic diagnostics - factual data relevant to the investigation (people, objects, substances, their properties, states, time, place).

The tasks of forensic diagnostics are classified into:

1) establishment of the spatial structure of the situation of the criminal event;

2) establishing the mechanism of individual stages of the event;

3) determination of the material structure of the environment of the scene;

4) establishment of temporal characteristics of a criminal event;

5) study of cause-and-effect relationships and forecasting their action;

6) determination of the properties of existing objects;

7) restoration of the mechanism of the criminal event as a whole.

Diagnostic studies are divided into:

1) identification of the properties and states of the object during its direct study (for example, whether the seal was broken after the initial sealing);

2) determination of the properties and state of the object by its display (for example, the state of the person who compiled a certain document);

3) analysis of the situation as a whole, when after studying the state of objects, their reflections, their relationship is established, the presence of a connection between individual phenomena and with the crime event.

The structure of the process of forensic diagnostics:

1) goal definition;

2) preliminary study of objects;

3) analysis of diagnostic features;

4) comparison by analogy;

5) evaluation and correction of the obtained results;

6) formulation of conclusions.

Diagnostics, like identification, is based on the study of the features of objects, but unlike identification, diagnostics focuses on the mechanism and conditions for the formation and display of traces.

A characteristic difference between diagnostics and identification is that during identification, the object being checked always exists materially, while during diagnostics this may not be the case.

Diagnosed object - this is an established condition (object, situation), and diagnostic objects are material carriers of signs that reflect properties (a system of properties, signs, etc.) and the impact on them of certain conditions of the event that occurred.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Flying over Venus 18.02.2011

The European space probe "Venus Express", circling around Venus since April 2006, measured the density of its upper atmosphere in an unusual way.

The control center, located in Darmstadt (Germany), deployed one of the two solar panels of the device "upright" - so that it stood across the direction of its movement, and the other remained parallel to the course. Then the probe's orbit was lowered closer to the surface of the planet, to a height of 175 kilometers from it, and they began to watch how the device tends to turn under the oncoming flow of Venusian air.

According to the results of measurements, the atmosphere in the circumpolar regions at such a height turned out to be 60% more rarefied than previously thought.
