Wyoming DOT Makes use of GIS to Cut back Truck Blow-Overs


Wyoming faces important challenges with climate circumstances on its interstate highways, significantly as a consequence of its location within the Rocky Mountains area. The state’s three main interstates usually endure extreme climate, making journey troublesome and dangerous. 

Extreme climate heightens crash dangers, resulting in delays, disrupting visitors circulate, and growing street upkeep prices. These points are exacerbated by the impacts of local weather change, making the scenario more and more troublesome.

The climate isn’t just an area difficulty. Wyoming’s interstates function key nationwide truck routes: two run coast to coast, whereas the third connects the state to New Mexico and Colorado from north to south.

Round 50 to 80 % of the visitors on Wyoming’s interstates are vehicles, that are significantly weak to excessive winds and automobile blow-overs. These crashes have averaged at virtually 170 per yr between the 2020-2022 interval. 

In Might 2023, the state’s Joint Committee on Transportation, Highways, and Navy Affairs raised these points as a severe concern. Earlier than the top of the yr, the Wyoming Division of Transportation (WYDOT) developed and carried out a GIS (Geographic Data System) to handle these distinctive challenges. 

The answer gives real-time alerts to business automobile (CV) homeowners and operators and introduces weight-based reasonably than blanket street closures.  

The preliminary outcomes of the answer have been encouraging, with solely seven blow-overs recorded between October 2023 and February 2024.  The WYDOT plans on making certain compliance by introducing a system of fines to discourage drivers from disregarding the alerts. 

The answer was developed by leveraging analysis undertaken by Dr. Noriaki Ohara, affiliate professor on the College of Wyoming’s School of Engineering & Bodily Sciences, and GIS software program from ESRI– one of many main suppliers of mapping and spatial analytics know-how. 

The growing variety of blow-overs outcomes from a number of elements together with adjustments in driver traits with extra skilled motorists on the roads. Some trucking corporations even encourage drivers to disregard street closures, promising to cowl fines if obligatory.

The prevalence of newer, lighter vehicles designed to save lots of on gasoline makes these automobiles extra vulnerable to blow-overs. As well as, the rise in empty vehicles getting back from distribution facilities in and round Cheyenne, the state capital, has additional intensified the difficulty.

“It’s not the heavy, absolutely loaded vehicles that are inclined to tip over,” says Nick Graf, geospatial challenge supervisor on the Wyoming DOT, “it’s the empty vehicles returning to the facilities which are actually problematic.”

In August 2023, the DOT consulted with the Wyoming Trucking Affiliation and obtained their consent for the brand new strategy to street closures. The primary weight-based street closure was then carried out on October 25.

Dr. Ohara’s analysis on the physics of blow-over crashes used information from the climate station on I-25 at Wyo Hill. This information is extrapolated throughout the state’s street networks by the WYDOT GIS group.

The brand new strategy makes use of “cones of threat” to evaluate automobile susceptibility to blow-overs, enhancing security by addressing beforehand ambiguous elements and their interactions associated to automobile and wind circumstances.

ArcGIS Professional from ESRI is crucial to this new answer, because it integrates real-time climate information from 94 statewide monitoring stations with roadway traits throughout the state. Moreover, the answer incorporates lidar information from Cyclomedia’s Road Sensible service to precisely map street slope angles and superelevation, which affect blow-over dangers.

By combining this information with street azimuth data, the group was capable of combine Ohara’s threat fashions into the system successfully.

The Transportation Administration Middle (TMC) workers handles the general public dissemination of knowledge generated by the system. They’re now capable of reply swiftly to climate occasions, with updates offered inside quarter-hour of any climate adjustments.

TMC makes use of varied media to speak data, together with a business automobile operator portal, social media video feeds, roadside indicators, and in-vehicle options. The message content material can also be changing into extra detailed, with particular weight restrictions communicated for various circumstances. 

WYDOT plans to combine the system with different programs, such because the 511-traveler data hotline. One other intention is to create self-evaluation options permitting drivers to enter their automobile data to find out which restrictions apply to them for present climate circumstances. Additional spatial variables may be included within the system, equivalent to automobile trip top above the bottom.

What has been happening between Zeekr and Cadillac over in China?!

There’s been somewhat little bit of trash speak happening over there in China between Zeekr and Cadillac. This follows some unhappiness amongst Zeekr clients after which Cadillac making an attempt to capitalize on that unhappiness — however not precisely nailing it. Right here’s the sequence of occasions and key components:

  1. Zeekr simply launched the 2025 Zeekr 007 sedan and 2025 Zeekr 001.
  2. These two new fashions are updates and enhancements over their predecessors, however they arrive nearly 6 months after these predecessors arrived available on the market.
  3. Zeekr house owners bought upset that their quite-new autos have been already being hit with huge depreciation attributable to these new variations popping out so quickly.
  4. Cadillac responded to that by posting a new-customer pitch on Weibo that particularly talked about itself as a Zeekr “substitute.” (Apparently, “ZEEKER REPLACEMNET” was Cadillac’s lead textual content within the Weibo publish, not solely misspelling “substitute” but additionally misspelling “Zeekr.”)
  5. That advertising try didn’t go over notably nicely. Zeekr VP Zhu Ling rotated and burned Cadillac. Zhu Ling famous that Cadillac was a traditional model, however that it was time to maneuver on. Extra particularly, he stated (in Chinese language): “The electrical age, the rise of China, the glory of Detroit is not any extra.”
  6. Additionally, seemingly responding to Cadillac and discussing the 007, he added: “It’s sooner than you, it’s smarter than you, it’s youthful than you, and it’s extra reasonably priced than you. Time doesn’t return, historical past doesn’t return. See you in my mirror.”

Them are fightin’ phrases.

Cadillac pulled down its publish quickly after it went viral, however “Cadillac vs Zeekr” grew to become a trending matter on Weibo.

The bottom model of the 007 prices simply RMB 209,900 ($29,400) and has 310 kW of energy. And simply take a look at the factor!

Swift delegate design sample – The.Swift.Dev.

Swift delegate design sample – The.Swift.Dev.



· 1 min learn

The delegate design sample is a comparatively straightforward approach to talk between two objects by way of a standard interface, protocol in Swift.

Implementing delegation in Swift

You’ll want a delegate protocol, a delegator who really delegates out the duties and a delegate object that implements the delegate protocol and does the precise work that was requested by the “boss”. Let’s translate this into human.

The consumer studies a bug. The undertaking supervisor creates a problem and tells one of many builders to repair the issue asap.

See? That’s delegation. Sooner or later an occasion occurred, so the delegator (supervisor) utilized an exterior useful resource (a developer) utilizing a standard interface (problem describing the issue for each occasion) to do obtain one thing (repair the 🐛).

To show how delegation works in actual life I made a reasonably easy instance. I’m going to make use of an analogous strategy (as a result of Xcode playgrounds are nonetheless freezing each 1-5 minutes) like I did for the command sample, however the objective of this one goes to be virtually completely completely different, as a result of we’re speaking about delegation. 😅

#!/usr/bin/env swift

import Basis


protocol InputDelegate {

    var shouldContinueListening: Bool { get }

    func didStartListening()
    func didReceive(enter: String)
}


class InputHandler {

    var delegate: InputDelegate?

    func pay attention() {
        self.delegate?.didStartListening()

        repeat {
            guard let enter = readLine() else {
                proceed
            }
            self.delegate?.didReceive(enter: enter)
        }
        whereas self.delegate?.shouldContinueListening ?? false
    }
}


struct InputReceiver: InputDelegate {

    var shouldContinueListening: Bool {
        return true
    }

    func didStartListening() {
        print("👻 Please be good and say "hello", if you wish to depart simply inform me "bye":")
    }

    func didReceive(enter: String) {
        change enter {
        case "hello":
            print("🌎 Whats up world!")
        case "bye":
            print("👋 Bye!")
            exit(0)
        default:
            print("🔍 Command not discovered! Please attempt once more:")
        }
    }
}

let inputHandler = InputHandler()
let inputReceiver = InputReceiver()
inputHandler.delegate = inputReceiver
inputHandler.pay attention()

That is how one can create your personal delegate sample in Swift. You’ll be able to think about that Apple is doing the identical factor below the hood, with UICollectionViewDataSource, UICollectionViewDelegate and many others. You solely need to implement the delegate, they’ll present the protocol and the delegator. 🤔

Weak properties, delegates and courses

Reminiscence administration is a vital factor so it’s price to say that each one the category delegates must be weak properties, otherwise you’ll create a very dangerous retain cycle. 😱

protocol InputDelegate: class { /*...*/ }

class InputHandler {

    weak var delegate: InputDelegate?

    /*...*/
}

class InputReceiver: InputDelegate {
    /*...*/
}

Right here is the altered Swift code snippet, however now utilizing a category because the delegate. You simply have to alter your protocol slightly bit and the property contained in the delegator. All the time use weak delegate variables if you’re going to assign a category as a delegate. ⚠️

As you may see delegation is fairly straightforward, however it may be harmful. It helps decoupling by offering a standard interface that can be utilized by anybody who implements the delegate (generally information supply) protocol. There are actually wonderful articles about delegates, when you’d wish to know extra about this sample, you must test them out.

Samsung Galaxy Ring teardown sheds mild on disposable tech not meant to final over two years


Purchaser beware: Samsung’s new Galaxy Ring and related finger-worn wearables symbolize the most recent class of wearable tech designed to entice shoppers. Earlier than opening up your pockets for a modern new sensible ring, nevertheless, you must know that you simply’re shopping for what’s primarily disposable expertise.

As iFixit highlights in its newest teardown, the Galaxy Ring – like all different sensible rings – is hamstrung by the truth that its lithium battery cannot be changed with out destroying the machine. In essence, Samsung’s well being monitoring ring has a shelf life and as soon as the battery is worn out, your solely plan of action is to toss out your complete factor.

How lengthy do you’ve gotten? Nicely, that relies upon. iFixit notes that the chemistry in trendy consumer-grade lithium-ion batteries are normally good for at the least 400 cycles. For many, this implies the $400 Galaxy Ring will not final greater than about two years with common use. Something past that needs to be thought of icing on the cake.

iFixit does not advocate shopping for disposable tech like this however in case you do, know that you simply’re at the least getting some neat – albeit, not earth-shattering – {hardware}.

The staff lately labored with engineers at Lumafield, and subjected a Galaxy Ring to a computed tomography (CT) scanner to get a have a look at the wearable’s inside workings with out dismantling it.

Curiously sufficient, the scan revealed using a press connector becoming a member of the battery to the circuit board. It is an odd design resolution contemplating the battery just isn’t replaceable. Why not merely solder it to the board? Maybe Samsung went this path to make meeting simpler and sooner.

Decided to dig deeper, iFixit cracked open the Galaxy Ring utilizing warmth and a dental choose to soften and chip away on the resin and plastic coating awaiting on the within. After confirming a press connector is certainly used to hyperlink the battery and inductive coil to the circuit board, they’d a more in-depth have a look at the battery.

It was too far broken to positively ID its capability however in response to Samsung’s web site, a dimension 11 ring ought to have a 19.5 mAh battery (curiously sufficient, battery capability scales with ring dimension).
