Authors: Setiawan Deni , Sari Marti Widya , Hardyanto R.Hafid 
Published: March 2021

Abstract
The risk of losing pets, especially pets without a leash, usually occurs because animals get lost or stolen by irresponsible people. Owners can look for themselves to the nearest environment, ask people around, to make announcement posters at strategic places. Searching in this way takes a lot of time and effort and the pets you are looking for are not necessarily found immediately. So we need an application and an animal tracking device in order to find out the location of the animal’s whereabouts, one of which is by using a tracking device that utilizes the Global Positioning System (GPS). This study aims to implement geofencing technology for pet tracking using Android-based Arduino. The application development stage includes analysis, system design, implementation, and testing. This program is implemented using U-Blox Neo 6M to track location with GPS network, SIM800L is used to send coordinate point data to trackers using GPRS network, and Arduino pro mini to manage input and output processes from the system. The test results show the tools and applications can run well. The android based pet tracker that is made can receive notification when a pet goes out of a predefined geofence limit.

Published: March 2021

Abstract
After regional autonomy has been implemented in Indonesia, local governments must maximize its revenue through various sectors, including the Bantul Regency government. One source of regional income is a local tax, based on law no 28 of 2009, one type of tax-managed by local government is the parking tax. Either an off-street parking lots, those provided in connection with the business principal, those provided as a business, or motor vehicle daycare (Indonesian Law No.28 of 2009). The parking tax is a self-assessment tax. Taxpayers will calculate their amount of tax that must be paid to the government. Therefore, the local government should conduct oversight of the reports of taxpayers. One form of supervision carried out is to monitor the number of vehicles at the taxpayer’s location. Officers then record the number of vehicles based on vehicle classification, whether they were two-wheeled or four-wheeled vehicles or other vehicle types. Currently, monitoring is done manually using a mechanical counter. This monitoring may have the risk of being miscalculated or wrongly recorded due to the monitoring officer’s oversight. Computer vision (OpenCV library) and machine learning (Mask R-CNN), is expected to minimize these errors and optimize the officers’ performance on duty.

Electron lenses: historical overview and outlook
Authors: Shiltsev V. 
Published: March 2021

Abstract
The first electron lenses — understood as “lenses made of
electrons” rather than “lenses to focus electrons” — were
envisioned in the mid-1990s and built in the early 2000s for
compensation of beam-beam effects in the Tevatron proton-antiproton
collider. Since then, the lenses — a novel instrument for
high-energy particle accelerators — have been added to the toolbox
of modern beam facilities, being particularly useful for the energy
frontier superconducting hadron colliders (“supercolliders”). In
this article we briefly present the history of ideas and
developments toward effective use of low-energy high-current bright
electron beams in high energy accelerators and discuss the promise
of their future applications.
McMillan electron lens in a system with space charge
Authors: Nagaitsev S. , Lobach I. , Stern E. , Zolkin T. 
Published: March 2021

Abstract
Space charge (SC) forces of a circulating beam in a ring
have both linear (defocusing) and nonlinear components, due to a
nonuniform beam distribution. The linear component of SC forces
produces a betatron tune shift, which is the largest for a
zero-amplitude particle, while the nonlinear component produces an
amplitude-dependent betatron tune spread. These SC effects are
responsible for several undesirable phenomena in accelerators:
emittance growth, particle losses, beam halo, etc. In this paper,
we investigate the possibility to mitigate the distributed SC forces
by a thin McMillan lens, providing an axially-symmetric kick, which
is qualitatively opposite to the accumulated effect of beam's own
SC. Experimentally, the proposed concept can be tested in Fermilab's
IOTA ring. A thin McMillan lens can be implemented by a short
(70) insertion of an electron beam with a specifically
chosen density distribution in transverse directions. In this
article, to test if McMillan lenses can reduce the tune spread
induced by SC, we make several simulations with a 6-D particle
tracking code, Synergia. We choose such beam and lattice parameters
that the SC tune spread is roughly 0.5 and the emittance growth due
to the half-integer resonance is clearly observed without the SC
compensation. Then, we focus on reducing the emittance growth by
adjusting the bare betatron tunes using the ring quadrupoles, and
reducing the tune spread by the McMillan lenses. The results of
reducing a large tune spread (≈ 0.5), reported here, are not
perfect, but substantial. There is still room for further
investigation. The simulations performed so far indicate that
McMillan lenses can cope with an SC tune spread of ≈ 0.1 per
lens.

Comparison of regulatory approaches for determining application limits for nitrogen fertilizer use in Germany
Authors: Löw Philipp , Osterburg Bernhard , Klages Susanne 
Published: March 2021

Abstract
This study examined the suitability of three different indicators as entry points for agricultural regulation for limiting excess nitrogen (N) fertilizer inputs in Germany: net soil surface balance, gross farm-gate balance, and fertilization planning. Data on about 6000 farms in Germany were grouped into types for comparative analysis. The design of the regulatory approaches and the reliability of constituent parameters were then examined, and proportions of affected farms and mean N reduction requirements were identified. This revealed that: (a) design and purpose of the regulatory approaches differ, but the data requirements are very similar; (b) the parameters involved differ in reliability and integrity; and (c) the limits for maximum N fertilizer input at farm level vary with approach and farm type.
Generalized symmetries and integrability conditions for hyperbolic type semi-discrete equations
*
Authors: Garifullin Rustem N , Habibullin Ismagil T 
Published: March 2021

Abstract
In the article differential-difference (semi-discrete) lattices of hyperbolic type are investigated from the integrability viewpoint. More precisely we concentrate on a method for constructing generalized symmetries. This kind integrable lattices admit two hierarchies of generalized symmetries corresponding to the discrete and continuous independent variables n and x. Symmetries corresponding to the direction of n are constructed in a more or less standard way while when constructing symmetries of the other form we meet a problem of solving a functional equation. We have shown that to handle with this equation one can effectively use the concept of characteristic Lie–Rinehart algebras of semi-discrete models. Based on this observation, we have proposed a classification method for integrable semi-discrete lattices. One of the interesting results of this work is a new example of an integrable equation, which is a semi-discrete analogue of the Tzizeica equation. Such examples were not previously known.
