With many construction sites remaining operational during the COVID-19 pandemic, it is extremely important to maintain compliance with all social distancing guidelines and requirements. NECA developed recommendations that are specific to construction projects that continue to be operational. While these are fairly comprehensive, they are not all-inclusive. The needs of each site can vary. State or other local requirements can be more restrictive and would take precedent.

1. NECA Helps Secure Construction Industry Exemption in Final IRAP Rule

On March 10, 2020, the Department of Labor released the final rule of the Industry-Recognized Apprenticeship Programs (IRAP) regulation. The final rule contains a permanent construction industry exemption, thereby protecting our industry from participation in IRAPs. NECA released a statement thanking the Administration for recognizing that the construction industry has longstanding expertise in the creation and execution of apprenticeships.

NECA’s Look Ahead: NECA strongly advocated for the construction industry’s exemption, with thousands of NECA contractors sending comments to the Department of Labor. By securing this exemption, the long-established, gold standard apprenticeship model that NECA Contractors utilize will remain intact and not be subjected to these parallel programs which will operate with less scrutiny and limited educational requirements.

2. The House Introduces Legislation to Address COVID-19 Outbreak

Washington D.C., like the rest of the nation and world, is responding to the outbreak of the COVID-19 (Coronavirus). On the evening of March 11, President Trump addressed the nation live from the  Oval Office. On Capitol Hill, negotiators continue to work to find a compromise between competing coronavirus response bills.

NECA’s Look Ahead: In response to the crisis, the Senate plans to cancel a previously scheduled recess week. The House will gavel out today and will return to Washington D.C. on March 23, 2020 to finish the negotiations on a final response package. NECA CEO, David Long, released the following statement in response to the legislative and regulatory negotiations: “ NECA government affairs remains fully engaged with Members of Congress, the Department of Labor, and OSHA on how to best handle the COVID-19 outbreak with safety being a top concern for our contractors and their employees. We continue to monitor legislation coming out of Congress to address the economic impact of this outbreak and will inform our contractors on how to best work with the new regulations when they are finalized.”

3. NLRB Chairman Testifies Regarding Funding      

On March 11, 2020, the House Committee on Appropriations held a hearing on the National Labor Relations Board Budget Request for FY 2021. Testifying on behalf of the NLRB was the Honorable John Ring, Chairman of the National Labor Relations Board. The NLRB budget request and justification documents can be found here.

NECA’s Look Ahead: The NLRB’s FY 2021 budget request funds their mission to protect the rights of employees, unions, and employers under the National Labor Relations Act (NLRA). NECA believes that lawmakers should continue to fully fund the NLRB and encourage their leadership to expedite the hiring of their regional offices.

Highlighting some of humanity’s biggest construction achievements is the 10 of the Top Construction Projects in the World informational infographic from 53 Quantum.

Human societies have always looked to build the biggest and best monuments to their ingenuity, resources and craftsmanship. From the Empire State Building, to the Eiffel Tower, and the Great Pyramids of Giza to the Great Wall of China, we’ve always looked to build the biggest and best. Mind blowing historic building projects now litter travel-minded folks bucket lists everywhere, and they make up a huge part of the historic tapestry.

But it’s 2019 now. We need to talk about the Burj Khalifas and Libyan Irrigation projects of the world. For the first time in history, there are societies wealthy, powerful, and most importantly, cohesive enough to build spectacularly huge projects. By working together with our geographical neighbours, we’ve been able to give the world some truly unbelievable, innovative projects. The International Space Station leaps to mind as a collaboration between nations.

With so many stunning projects continually on the go around the planet, we at 53 Quantum thought it’d be an idea to put together a quick infographic of ten of the biggest and best. Of course, there’ll be examples we missed and things we left off, because how do you compare a massive railway restoration and modernisation with a super skyscraper project? Apples and oranges!

Nevertheless, here are ten of the world’s most impressive construction projects.

Although I like the infographic, this design falls short in a few areas.

• Where’s the Data Visualization? The biggest missed opportunity in this design is that the data isn’t visualized. You want readers to understand how big or how expensive these projects were, you need a visualization that puts that into context!

• Nice illustrations, but that isn’t enough. Most of the impact of the size and scale of these projects is lost because it’s buried in the text.

• A map of the locations would be nice.

• Is there any logic to the order of these projects in the infographic? Readers will look through the list from top-to-bottom in order. They’re not sorted by cost or on a timeline.

This paper addresses the problem of identifying the graph structure of a dynamical network using measured input/output data. This problem is known as topology identification and has received considerable attention in recent literature. Most existing literature focuses on topology identification for networks with node dynamics modeled by single integrators or single-input single-output (SISO) systems. The goal of the current paper is to identify the topology of a more general class of heterogeneous networks, in which the dynamics of the nodes are modeled by general (possibly distinct) linear systems. Our two main contributions are the following. First, we establish conditions for topological identifiability, i.e., conditions under which the network topology can be uniquely reconstructed from measured data. We also specialize our results to homogeneous networks of SISO systems and we will see that such networks have quite particular identifiability properties. Secondly, we develop a topology identification method that reconstructs the network topology from input/output data. The solution of a generalized Sylvester equation will play an important role in our identification scheme.

This work presents a novel data-driven framework for constructing eigenfunctions of the Koopman operator geared toward prediction and control. The method leverages the richness of the spectrum of the Koopman operator away from attractors to construct a rich set of eigenfunctions such that the state (or any other observable quantity of interest) is in the span of these eigenfunctions and hence predictable in a linear fashion. The eigenfunction construction is optimization-based with no dictionary selection required. Once a predictor for the uncontrolled part of the system is obtained in this way, the incorporation of control is done through a multi-step prediction error minimization, carried out by a simple linear least-squares regression. The predictor so obtained is in the form of a linear controlled dynamical system and can be readily applied within the Koopman model predictive control framework of [12] to control nonlinear dynamical systems using linear model predictive control tools. The method is entirely data-driven and based purely on convex optimization, with no reliance on neural networks or other non-convex machine learning tools. The novel eigenfunction construction method is also analyzed theoretically, proving rigorously that the family of eigenfunctions obtained is rich enough to span the space of all continuous functions. In addition, the method is extended to construct generalized eigenfunctions that also give rise Koopman invariant subspaces and hence can be used for linear prediction. Detailed numerical examples with code available online demonstrate the approach, both for prediction and feedback control.

A perfect matroid design (PMD) is a matroid whose flats of the same rank all have the same size. In this paper we introduce the q-analogue of a PMD and its properties. In order to do that, we first establish new cryptomorphic definitions for q-matroids. We show that q-Steiner systems are examples of q-PMD's and we use this matroid structure to construct subspace designs from q-Steiner systems. We apply this construction to S(2, 13, 3; q) Steiner systems and hence establish the existence of subspace designs with previously unknown parameters.

In this paper, we give new constructions of strongly regular Cayley graphs on abelian groups as generalizations of a series of known constructions: the construction of covering extended building sets in finite fields by Xia (1992), the product construction of Menon-Hadamard difference sets by Turyn (1984), and the construction of Paley type partial difference sets by Polhill (2010). Then, we obtain new large families of strongly regular Cayley graphs of Latin square type or negative Latin square type.

In this work we propose lifted regression/reconstruction networks (LRRNs), which combine lifted neural networks with a guaranteed Lipschitz continuity property for the output layer. Lifted neural networks explicitly optimize an energy model to infer the unit activations and therefore---in contrast to standard feed-forward neural networks---allow bidirectional feedback between layers. So far lifted neural networks have been modelled around standard feed-forward architectures. We propose to take further advantage of the feedback property by letting the layers simultaneously perform regression and reconstruction. The resulting lifted network architecture allows to control the desired amount of Lipschitz continuity, which is an important feature to obtain adversarially robust regression and classification methods. We analyse and numerically demonstrate applications for unsupervised and supervised learning.

This paper reviews the second challenge on spectral reconstruction from RGB images, i.e., the recovery of whole-scene hyperspectral (HS) information from a 3-channel RGB image. As in the previous challenge, two tracks were provided: (i) a "Clean" track where HS images are estimated from noise-free RGBs, the RGB images are themselves calculated numerically using the ground-truth HS images and supplied spectral sensitivity functions (ii) a "Real World" track, simulating capture by an uncalibrated and unknown camera, where the HS images are recovered from noisy JPEG-compressed RGB images. A new, larger-than-ever, natural hyperspectral image data set is presented, containing a total of 510 HS images. The Clean and Real World tracks had 103 and 78 registered participants respectively, with 14 teams competing in the final testing phase. A description of the proposed methods, alongside their challenge scores and an extensive evaluation of top performing methods is also provided. They gauge the state-of-the-art in spectral reconstruction from an RGB image.

Thin structures, such as wire-frame sculptures, fences, cables, power lines, and tree branches, are common in the real world.

It is extremely challenging to acquire their 3D digital models using traditional image-based or depth-based reconstruction methods because thin structures often lack distinct point features and have severe self-occlusion.

We propose the first approach that simultaneously estimates camera motion and reconstructs the geometry of complex 3D thin structures in high quality from a color video captured by a handheld camera.

Specifically, we present a new curve-based approach to estimate accurate camera poses by establishing correspondences between featureless thin objects in the foreground in consecutive video frames, without requiring visual texture in the background scene to lock on.

Enabled by this effective curve-based camera pose estimation strategy, we develop an iterative optimization method with tailored measures on geometry, topology as well as self-occlusion handling for reconstructing 3D thin structures.

Extensive validations on a variety of thin structures show that our method achieves accurate camera pose estimation and faithful reconstruction of 3D thin structures with complex shape and topology at a level that has not been attained by other existing reconstruction methods.

The de Bruijn graph, its sequences, and their various generalizations, have found many applications in information theory, including many new ones in the last decade. In this paper, motivated by a coding problem for emerging memory technologies, a set of sequences which generalize sequences in the de Bruijn graph are defined. These sequences can be also defined and viewed as constrained sequences. Hence, they will be called constrained de Bruijn sequences and a set of such sequences will be called a constrained de Bruijn code. Several properties and alternative definitions for such codes are examined and they are analyzed as generalized sequences in the de Bruijn graph (and its generalization) and as constrained sequences. Various enumeration techniques are used to compute the total number of sequences for any given set of parameters. A construction method of such codes from the theory of shift-register sequences is proposed. Finally, we show how these constrained de Bruijn sequences and codes can be applied in constructions of codes for correcting synchronization errors in the $ell$-symbol read channel and in the racetrack memory channel. For this purpose, these codes are superior in their size on previously known codes.
