Some misunderstood or unknown LaTeX tricks (XVI) Merciadri, Luca E-print/Working paper (2015) This is the second (and last) part of the tricks I found on StackExchange. First part began in the preceding issue. We will begin by a personal trick, and end by some inquiry about my LaTeX Tips & Tricks.

Tricks: vertically aligned itemize environments, allowing linebreaks after comma in math mode, writing under and over elements, and using stacks, footnotes with a new number at each section, footnotes in tabular, splitting algorithm environments on multiple pages, let " produce opening/closing quotation marks, indenting some text but not the first line, using diagonal dots positioned according to the opposite diagonal, using a centered verbatim environment, drawing a table with dashed lines, shaded cells and arrows pointing at a row and a column, correct spacing around square brackets (used for sets) in math mode.

This time, we shall first see how to write `dancing text,' roman numerals, how to draw under and over braces on same elements, and how to display aligned (in)equations systems. We will then end by discussing on BibLaTeX and Biber, which constitute a promising alternative to BibTeX.

Detailed reference viewed: 37 (16 ULg)Some misunderstood or unknown tricks (XI) (LaTeX) and encoding issues (II) Merciadri, Luca E-print/Working paper (2015) Three subjects will be detailed: 1. Using LaTeX syntax as an unambiguous way to communicate, 2. Writing a bold \ell, 3. Fonts' encodings. Detailed reference viewed: 4 (1 ULg)Optimal Assignment of Off-Peak Hours to Lower Curtailments in the Distribution Network Merciadri, Luca ; Mathieu, Sébastien ; Ernst, Damien et al in Proceedings of the 5th European Innovative Smart Grid Technologies (ISGT) (2014, October) We consider a price signal with two settings: off-peak tariff and on-peak tariff.

[more ▼] We consider a price signal with two settings: off-peak tariff and on-peak tariff. Some loads are connected to specific electricity meters which allow the consumption of power only in off-peak periods. Historically, off-peak periods were located during the night and on-peak periods during the day. Changing the assignment of off-peak periods is an easy method for distribution system operators to access to the flexibility of small consumers. This solution can be implemented quickly as the infrastructure needed already exists in some countries. We propose a mixed-integer linear model to assign optimally the off-peak hours so as to minimize a societal cost. This cost gathers together the cost of electricity, the financial losses due to energy curtailments of photovoltaic installations and the loads' wellbeing. Our model considers automatic tripping of inverters and constraints of the electrical distribution networks. Simulation results show that the new disposition of off-peak hours could reduce significantly the photovoltaic energy curtailed in the summer.

[more ▼] In this Master’s thesis, the influence of PhotoVoltaic (PV) panels on the distribution network is explained and related available solutions are also mentioned. We focus on a solution which consists of optimally using flexible loads. We consider a price signal with two settings: off- peak tariff and on-peak tariff. Some suitable loads are connected to specific electricity meters, called ‘night-only meters,’ which allow the consumption of power only in off-peak periods. We describe the meters’ characteristics and the suitable loads. We also discuss the aspects related to the practical implementation. Historically, off-peak periods were located during the night and on-peak periods during the day. Changing the assignment of off-peak periods is an easy method for distribution system operators to access to the flexibility of small consumers. This solution can be implemented quickly as the infrastructure needed already exists. We propose a mixed-integer linear model to assign optimally the off-peak hours so as to maximize a social welfare. This welfare gathers together the cost of electricity, the financial losses due to energy curtailments of PV installations and the loads’ wellbeing. Our model considers automatic tripping of inverters and constraints of the electrical distribution networks. We target night-only meters, but an extension to dual-hourly meters is also presented. The results compare the application of the classical pattern against the optimal one for summer and winter days, the influence of the available variable power for a summer day, and the use of a monthly-optimal pattern against the classical one for a summer month. The new disposition of off-peak hours can reduce by 50% the PV energy curtailed in the summer, and can also help reducing the power flow going through the High-Voltage (HV)/Medium-Voltage (MV) transformer. The document ends by a cost analysis comparing the homes’ money gains in two main cases: classical pattern and monthly-optimal one, for a summer month. For each case, the Distribution System Operator (DSO) either refunds curtailments or not. Four different types of homes are considered: with or without night-only meters, with or without PV. This analysis allows to know rapidly who earns money and who looses money by getting plausible values of electricity bills.

Referring to \labels by long names. We will then discuss some problems people often face when dealing with many figures, and, more generally, floats, in reports. Finally, we will deal with a Beamer scheme which aims at using a single file for both a presentation, and the related report.

There are those who prefer traditional printed books, but there is also a growing audience whose lifestyle and taste is suited to eBooks. We discuss some advantages of using eBooks, and creating them with LaTeX. We continue by explaining technical aspects that might improve and help you with your LaTeX eBook. We end with a short discussion about the PDF file format and its use with eBook documents.

[more ▼] Writing a document is a difficult task because the writer needs to think about two different concepts: the appearence of the document, and its content. Both constitute the message the writer wants to transmit. We will here treat about the aesthetics of publications, from the perspective of effectiveness (which implies clarity). We begin by discussing some (but not all!) basic principles on how to write a good article, then treat about what LaTeX can help you to do to improve your document's content. We end with what you might do and do not about graphical \ae sthetism, and then end with some tips on how to ensure aesthetism, together with effectiveness, when writing an article.

[more ▼] I have written three LaTeX2e packages, namely bigints, dashundergaps, and plantslabels. Because there are so many submitted packages, TeX-information sources are so used that communications rapidly go to the archives, their respective emergences could have been unoticed by the majority of the Community. I here propose a brief summary about what they do, and how they could be useful for your work.

[more ▼] A Latin square of order n^2 is a Sudoku matrix if subdividing its entries into n^2 disjoint n-by-n subblocks causes each symbol to appear once in each subblock. Symbols are taken from {1, ..., n^2}, and n^2 = 9 then corresponds to the familiar recreation. A construction of cyclic latin squares (see Shiu, W.C. and Fang, K.T. and Ma, S. L., On the Rank of Cyclic Latin Squares, Linear and Multilinear Algebra, Vol. 40, pp. 183-188) determines their minimum rank and shows they can attain full rank. It follows that Sudoku matrices can also be full rank. The present authors initially thought that the minimum ranks of Sudoku matrices would equal the minimum ranks of cyclic latin squares of the same order, i.e. 1 + \sum_{i=1}^{s} \varphi\left((p_i)^{t_i}\right) where n=\prod_{i=1}^{s} (p_i)^{t_i} is the prime factorization (of n), and \varphi is Euler's totient function. However, a block-cyclic latin square construction is found that attains a smaller rank. For the case n^2 = 9, one gets a rank 5 matrix rather than rank 7. Some generalizations such as taking symbols from {0, ..., n^2 -1} are discussed, and comparisons made to ranks of more general kinds of latin squares. We also discuss the possibility of finding a rank inferior to 5 for a 9*9 Sudoku matrix. (Until here, no test revealed such a possibility, but tests are not finished yet.)

[more ▼] On some examination sheets, some professors or lecturers like to indicate to the reader that the `page' can be turned. One might implement a LaTeX mechanism so that each odd page (except the last one, if any) displays a message to turn the page. This mechanism can also be useful for different kinds of documents. This package should thus be used for exams, or special documents printed `twoside.' [less ▲] Detailed reference viewed: 81 (16 ULg) |
