CutLang v2: Advances in a Runtime-Interpreted Analysis Description Language for HEP Data

We will present the latest developments in CutLang, the runtime interpreter of a recently-developed analysis description language (ADL) for collider data analysis. ADL is a domain-specific, declarative language that describes the contents of an analysis in a standard and unambiguous way, independent of any computing framework. In ADL, analyses are written in human-readable plain text files, separating object, variable and event selection definitions in blocks, with a syntax that includes mathematical and logical operations, comparison and optimisation operators, reducers, four-vector algebra and commonly used functions. Adopting ADLs would bring numerous benefits to the LHC experimental and phenomenological communities, ranging from analysis preservation beyond the lifetimes of experiments or analysis software to facilitating the abstraction, design, visualization, validation, combination, reproduction, interpretation and overall communication of the analysis contents. Since their initial release, ADL and CutLang have been used for implementing and running numerous LHC analyses. In this process, the original syntax from CutLang v1 has been modified for better ADL compatibility, and the interpreter has been adapted to work with that syntax, resulting in the current release v2. Furthermore, CutLang has been enhanced to handle object combinatorics, to include tables and weights, to save events at any analysis stage, to benefit from multi-core/multi-CPU hardware among other improvements. In this contribution, these and other enhancements are discussed in details. In addition, real life examples from LHC analyses are presented together with a user manual.

Recent advances in ADL, CutLang and adl2tnm

This paper presents an overview and features of an Analysis Description Language (ADL) designed for HEP data analysis. ADL is a domainspecific, declarative language that describes the physics content of an analysis in a standard and unambiguous way, independent of any computing frameworks. It also describes infrastructures that render ADL executable, namely CutLang, a direct runtime interpreter (originally also a language), and adl2tnm, a transpiler converting ADL into C++ code. In ADL, analyses are described in humanreadable plain text files, clearly separating object, variable and event selection definitions in blocks, with a syntax that includes mathematical and logical operations, comparison and optimisation operators, reducers, four-vector algebra and commonly used functions. Recent studies demonstrate that adapting the ADL approach has numerous benefits for the experimental and phenomenological HEP communities. These include facilitating the abstraction, design, optimization, visualization, validation, combination, reproduction, interpretation and overall communication of the analysis contents and long term preservation of the analyses beyond the lifetimes of experiments. Here we also discuss some of the current ADL applications in physics studies and future prospects based on static analysis and differentiable programming.

Penerapan Identifikasi Bahaya dan Manajemen Resiko Keselamatan di Bandar Udara Supadio - Pontianak

Safety and Security in Airports flight something that should not be ignored. To anticipate a situation that allows the occurrence of accident and incident, the airport operator and all units of the organization that is the environment of the airport should be able to identify hazards I problems based on events that never happened. The survey was conducted in Supadio Airport towards the application of hazard identification and safety risk management, using the method of comparative analysis and evaluation to make mengukuran of 13 variables. Based on measurements of 13 variables, obtained by 3 variables included in the criteria can not be accepted on condition that there is, namely a foreign object variable that has the potential to cause damage to the aircraft (foreign object damage 4.B), the variable things that can disrupt flights (obstacle 4.B), and variable in Apron vehicles (vehicle in Apron 5.C). Two criterion variables risk control/ mitigation requires a management decision that is, variable Noise (noise 5), and variable Security Issues (security issues. 2A). This value indicates that the 3 variables are included that are essential for risk reduction targets.Keywords: Airports, Safety Management System, hazard identification, safety risk

Relation of Relationship Between Research Theory and Variable with Management Case Study

In a management at Higher Education in conducting a scientific work research is a very important step, especially regarding the relationship between theory and research variables. On the provisions that have been applied to management in the previous Higher Education where the scientific work studied is not directed because there is no clear object variable. In this study review the subject matter of theory, components, and theoretical descriptions, concepts and constructs, understanding variables, with the results of research on various variables such as independent and dependent variables, intervening variables, moderator variables, and control variables, operational definitions, theoretical frameworks and frame of mind in research. by using 2 (two) research methods, namely direct observation on the results of student research, and the literature review described in the following study. So that it is expected that the existence of theory and variable research on management at the Higher Education can make scientific work more focused.

Study the Stability of Bending-Torsional Coupled Vibration of a Rotor System with a Crack and Variable Perturbation Method

The differential equations of bending-torsional coupled vibration have been established with a switching crack for a Jeffcott rotor system with a transverse crack as the research object. Variable perturbation method has been used to study the stability of bending-torsional coupled vibration of a rotor system with a crack. The theoretical result shows that, when it is close to the natural frequency of 2 times, 3/2 times and 1 times, unstable vibrations exist and conditions of stable vibration. According to the above order, unstable region becomes narrow. While in 1/4 times, 1/6 times, the system is stable. The conclusions provide valuable theoretical basis for a crack rotor system in the real working conditions when corresponding measures need taking.
